Hydride Reduction of the Cations <(eta5-C5H5)Fe<(Ph2PCH2)3CMe>>PF6, <(eta5-C5H5)Ru<(Ph2PCH2CH2)2PPh>>PF6, and <(eta5-C5H5)Ru<(Ph2PCH2)3CMe>>PF6: Regioselectivity and Mechanism

Reduction of the cation <(eta5-C5H5)Fe(tripod)>PF6 with lithium aluminium hydride gives (eta5-C5H5)FeH(tripod) via an SN1 mechanism, involving prior dissociation of a phosphine ligand leading to direct attack of hydride on the metal, in contrast with the related ruthenium cations <(eta5-C5H5)RuL3>PF6 (L3 = triphos or tripod) which give the cyclopentadiene complexes (eta4-C5H6)RuL3 via exo-hydride attack on the cyclopentadienyl ligand .

Synthesis, transition metal chemistry and catalytic reactions of ferrocenylbis(phosphonite), [Fe{C5H4P(OC6H 3(OMe-o)(C3H5-p))2}2]

The new metalloligand ferrocenylbis(phosphonite), [Fe(C5H 4PR2)2 (R = OC6H3(OMe-o) (C3H5-p))], (2), is synthesized by the reaction of bis(dichlorophosphino)ferrocene Fe(C5H4PCl 2)2 (1) with 4-allyl-2-methoxyphenol. The reactions of 2 with H2O2 and elemental sulfur or selenium afforded bischalcogenides, [Fe{C5H4P(E)(OC6H 3(OMe-o)(C3H5-p))2}2] (3, E = O; 4, E = S; 5, E = Se), in good yield. The bis(phosphonite) reacts with group 6 metal carbonyls and group 10 metal dichloride precursors to produce the chelate complexes [{M(CO)4}Fe{C5H4P(OC 6H3(OMe-o)(C3H5-p)) 2}2}] (6, M = Mo; 7, M = W) and [(MCl2) Fe{C5H4P(OC6H3(OMe-o)(C 3H5-p))2}2] (8, M = Pd; 9, M = Pt). The palladium(ii) complex [(PdCl2)Fe{C5H 4P(OC6H3(OMe-o)(C3H 5-p))2}2] (8) is an efficient catalyst for the Suzuki-Miyaura cross-coupling reactions (TON up to 1.5 ¡Á 105). The reaction of 2 with one equivalent of [RuCl2(eta6-p- cymene)]2 yielded the binuclear complex [{Ru2Cl 4(eta6-p-cymene)2}Fe{C5H 4P(OC6H3(OMe-o)(C3H 5-p))2}2] (12) in good yield. Treatment of 2 with copper chloride in a 1:1 or 1:2 molar ratio resulted in the formation of a binuclear complex, [{(CuCl)Fe{C5H4P(OC6H 3(OMe-o)(C3H5-p))2} 2}2] (13), whereas a similar reaction of 2 with CuBr and CuI in a 1:2 or 1:2.5 molar ratio yielded the novel butterfly-like deca-nuclear complexes [Cu5(mu-X)5{Fe{C5H 4P(OC6H3(OMe-o)(C3H 5-p))2}2}2]2 (14, X = Br; 15, X = I). The reaction of 2 with two equivalents of [AuCl(SMe2)] afforded the digold complex [(AuCl)2Fe{C5H 4P(OC6H3(OMe-o)(C3H 5-p))2}2] (16), with the ligand exhibiting bridged-bidentate mode of coordination. Additionally, some complexes were studied by cyclic voltammetry. The crystal structures of complexes 8, 9, 12, 15 and 16 were determined using X-ray diffraction studies.

Synthesis, electrochemistry, and reactivity of half-sandwich ruthenium complexes bearing metallocene-based bisphosphines

The bimetallic complexes CpRu(P-P)X [Cp = n5-C5H 5; X = Cl, H; P-P = dppf (1,1?-bis(diphenylphosphino)ferrocene) , dppr (1,1?-bis(diphenylphosphino)ruthenocene), dppo (1,1?- bis(diphenylphosphino)-osmocene), dippf (1,1?-bis(diisopropylphosphino) ferrocene), dcpf (1,1?-bis(dicyclohexylphosphino)ferrocene)], Cp*Ru(P-P)X [Cp* = n5-C5Me5; X = Cl, H; P-P = dppf, dippf, dppomf (1,1?-bis(diphenylphosphino) octamethylferrocene), dppc (1,1?-bis(diphenylphosphino)cobaltocene)], [Cp*Ru(P-P)X]+ (X = H, CCPh; P-P = dppc+), and [Cp*Ru(P-P)L]2+ (L = CH3CN, t-BuCN; P-P = dppc -) have been synthesized. Most of the chloride and hydride complexes have been studied by cyclic voltammetry. The X-ray structures of [Cp*Ru(dppc)CH3CN][PF6]2 and [Cp*Ru(dppc)CCPh] [PF6] have been determined. Protonation of [Cp*Ru(dppc)CCPh] + gives the vinylidene complex [Cp*Ru(dppc)CCHPh]2+. The Co(III/II) potential of the dppc+ ligand undergoes a cathodic shift upon coordination in [Cp*Ru-(dppc)H]+ and an anodic shift upon coordination in [Cp*Ru(dppc)CH3CN] . The 1H NMR spectrum of Cp*Ru(dppc)H is consistent with its formulation as a Co(II)/Ru(II) complex. As gauged by their reactivity toward iminium cations, the hydride complexes are poor hydride donors; proton and electron transfer are dominant. CpRu(dippf)H and CpRu(dcpf)H deprotonate iminium cations with acidic a-hydrogens. Cp*Ru(dppc)H is oxidized by the N-(benzylidene)pyrrolidinium cation, giving [Cp*Ru-(dppc)H]- and the vicinal diamine 1,2-bis(N-pyrrolidino)-1,2-diphenylethane. Most of the hydride complexes give rraw-dihydride cations upon protonation; an exception is [Cp*Ru(dppc)H] +, which forms a dihydrogen complex [Cp*Ru(dppc)(H2)]2+ with surprising kinetic stability. This dihydrogen complex is more acidic and less thermodynamically stable than its dihydride isomer. The H2 ligand in [Cp*Ru(dppc)-(H2)]2+ is readily replaced by nitriles; the reaction with t-BuCN occurs by a dissociative mechanism.

Binding and activation of halocarbons by iron(II) and ruthenium(II)

A series of cyclopentadienylruthenium(II) and -iron(II) complexes contain intact iodoalkanes, p-iodotoluene, or chelating (P, X) (o-halophenyl)diphenylphosphine (X = Cl, Br) ligands. The halocarbons coordinate via ?-donation of a halogen lone pair and retain their carbon-halogen bonds. The complexes are synthesized from the halocarbon, metal halide, and silver(I) ion. Full characterization shows that they are Ru(II) complexes of intact halocarbons rather than Ru(IV) products of oxidative addition. The crystal and molecular structure of one such complex, [Cp(CO)(PPh3)Ru(IC6H4-p-CH3)] PF6, is reported. The iodoalkanes are activated by coordination, and the complexes cleanly and rapidly alkylate a wide range of inorganic and organic nucleophiles. In particular, carbon-carbon bonds can be formed with C-nucleophiles such as enamines. The halocarbon complex can be much more selective than free halocarbon for C-alkylation over N-alkylation. The iodoalkane complexes undergo ligand substitution with common coordinating solvents to produce the corresponding solvento complexes. The haloarene complexes are displaced only by nucleophiles.

Reactions of the cationic fragments [RuCp(PPh2NHR) 2]+ and [RuTp(PPh2NHR)2]+ (R = Ph, re-Pr) with Alkynes: Formation of four-membered azaphosphacarbenes

The synthesis of RuCp(PPh2NHR)2Cl (1a,b; R = Ph, n-Pr) and RuTp(PPh2NHR)2Cl (2a,b) is reported. Chloride abstraction from 1a with AgCF3SO3 affords RuCp(PPh 2NHPh)2(eta1-OSO2CF3) (3), whereas when AgSbF6 is used instead [RuCp(kappa2(P, P)-PPh2NHC6H4PPh2)(NH 2-Ph)]+ (4) is formed. In the course of this reaction the P-N bond of one PPh2NHPh ligand is cleaved while a new P-C bond is formed, with concomitant formation of an aniline ligand. In the presence of Ag+ (CF3SO3- or SbF6 -) complexes 1 and 2 react with terminal alkynes HC?CR? (R? = Ph,p-C6H4Me, n-Bu) and propargylic alcohols to give novel azaphosphacarbene complexes of the types [RuCp(kappa 2(C,P)=C(CH2R?)N(R)PPh2) (kappa1(P)-PPh2NHR)]+ (5a-c, 6a-c), [RuTp(kappa2(C,P)=C(CH2R?)N(R)PPh 2)(kappa1(P)-PPh2NHR)]+ (14a,b, 15a-c), [RuCp(kappa2(C,P)= C(CH=CPh2)N(Pr n)PPh2)(kappa1(P)-PPh2NHPr n)]+ (12), and [RuTp(kappa2(C,P)=C(CH=CPh 2)N(Prn)-PPh2)(kappa1(P)-PPh 2NHPrn)]+ (17). These reactions proceed via vinylidene and allenylidene intermediates, respectively, which could be isolated in some cases: viz. [CpRu(PPh2NHPh)2-(=C=C=CPh 2)]+ (11) and [RuTp(PPh2NHR) 2(=C=C=CPh2)]+ (16a,b). Furthermore, complexes 1a,b react with 3-butyn-1-ol to yield the oxacyclopentylidene complexes [CpRu(PPh2-NHR)2(=C4H6O)] + (7a,b). In sharp contrast to 6a-c (R = n-Bu), 5a-c (R = Ph) turned out to be quite sensitive toward traces of water, leading eventually to the formation of the aminocarbene complexes [RuCp(=C(CH2R)NHPh)(PPh 2NHPh)(kappa1(P)-PPh2OH)]+ (8a,b) featuring a kappa1(P)-coordinated PPh2OH ligand. This ligand could be easily deprotonated to yield the neutral complex RuCp(=C(CH 2Ph)NHR)(PPh2NHPh)(kappa1(P)-OPPh 2) (10a,b). The formation of these complexes is reversible. Finally, representative structures have been determined by X-ray crystallography.

Cyclization of 2-Ethynylphenyl Vinyl Ether Catalyzed by a Ruthenium Complex: Mechanism of Catalytic Cyclization and Stoichiometric Cycloisomerization

Catalytic cyclization reactions and new stoichiometric skeletal rearrangement cycloisomerizations of 2-ethynylphenyl vinyl ethers containing methyl substituents on the vinyl groups by using [Ru]Cl {[Ru]=Cp(PPh3)2Ru, Cp=eta5-cyclopentadienyl} were observed in MeOH and CH2Cl2, respectively. In MeOH, the catalytic cyclization of three different enynes gave the corresponding benzoxepine derivatives in high yields in each case. Interestingly, in the stoichiometric reactions of [Ru]Cl with enynes, two unprecedented rearrangements of enynes were observed in CH2Cl2. The presence of a methyl group in the vinyl unit plays a critical role in choosing one of the double bonds of the vinylidene ligand, that is, the Ru=Calpha or the Calpha=Cbeta bond, for the [2+2] cycloaddition in the cycloisomerization processes. Structure determination by single-crystal X-ray diffraction analysis along with various isotope studies corroborated the proposed mechanisms.

Mono- and dinuclear maleonitriledithiolate and dibenzyldithiomaleonitrile complexes of (bipy)2Ru(II): synthesis, spectral and electrochemical study

[Ru(bipy)2{S2C2(CN)2}] and [Ru(bipy)2{(C6H5CH2)2S2C2(CN)2}][PF6]2 were synthesized by the reaction of [Ru(bipy)2Cl2]*2H2O with Na2S2C2(CN)2 or (C6H5CH2)2S2C2(CN)2 in aqueous ethanol, and used to form dinuclear species by binding Cp(PPh3)2Ru(II) or (bipy)2ClRu(II) moieties onto the CN nitrogen sites. Spectral and electrochemical properties of all complexes have been investigated. S2C2(CN)2(2-) is found to introduce a low lying dpi(Ru) .pi*.(S2C2(CN)2(2-)) MLCT state and an easily oxidizablecentre upon complexation. (C6H5CH2)2S2C2(CN)2 exhibits weaker pi acidity and imparts a 2852 cm**-1, 0.35 V lower stabilization to the ruthenium dpi orbitals than the saturated chain dithioether (CH3)2S2C2H2, as indicated in the Ru bipy MLCT absorption energy and the first oxidation potential of the corresponding (bipy)2Ru(II) complexes.

A new ruthenium cyclopentadienyl azole compound with activity on tumor cell lines and trypanosomatid parasites

(Chemical Equation Presented). As part of our efforts to develop organometallic ruthenium compounds bearing activity on both trypanosomatid parasites and tumor cells, a new Ru(II)-cyclopentadienyl clotrimazole complex, [RuCp(PPh3)2(CTZ)](CF3SO3), where Cp = cyclopentadienyl, CTZ = clotrimazole, was synthesized and characterized. The compound was evaluated in vitro on T. cruzi (Y strain), the infective form of T. brucei brucei strain 427 (cell line 449), on three human tumor cell lines with different sensitivity to cisplatin (A2780, ovary; MCF7, breast; HeLa, cervix) and on J774 murine macrophages as mammalian cell model. The new compound is more cytotoxic on T. cruzi and on the tumor cell lines than the reference drugs (Nifurtimox and cisplatin, respectively). In addition, complexation of the bioactive CTZ to the {RuCp(PPh3)} moiety leads to significant increase of the antiparasitic and antitumoral activity. To get insight into the potential “dual” mechanism of antiparasitic action emerging from the presence of Ru(II) and CTZ in a single molecule, the inhibitory effect of this new complex on the biosynthesis of T. cruzi sterols of membrane and the interaction with DNA were studied. Although the tested complex does not affect DNA, it affects the T. cruzi biosynthetic pathway of conversion of squalene to squalene oxide. According to the results reported here, [RuCp(PPh3)2(CTZ)][CF3SO3] could be considered a prospective antiparasitic and/or antitumoral agent that deserves further evaluation.
