Complexes of ruthenium containing 2-furan- and 2-thiophene-thiolates with phosphine ligands have been prepared and characterized. The bis(triphenylphosphine) complexes CpRu(PPh3)2SR (R = C4H3O: Fu (1a), C4H3S: Thi (1b)) were prepared by the reaction of thiolato anions (FuS- or ThiS-) with CpRu(PPh3)2Cl. The one-pot reaction of CpRu(PPh3)2Cl, thiolato anions and L ligands gave CpRu(L)SR (L = bis(diphenylphosphino)methane: dppm (2); bis(diphenylphosphino)ethane: dppe (3)). The newly prepared complexes have been characterized by spectroscopic techniques (FT-IR, 1H NMR and 31P NMR) and by elemental analysis. The crystal structure of CpRu(dppe)SThi (3b) has been determined by X-ray diffraction.

Treatment of the ruthenium chloride, CpRu(PPh3)2Cl, with the alkynyldithiocarboxylate anions, RCCCS2-, in refluxing THF affords the chelate complexes CpRu(PPh3)(kappa2S,S-S 2CCCR) (1) (R = But (a), Bun (b), Ph (c), SiMe3 (d)) in high yield. The room temperature reaction of the solvated species, [CpRu(PPh3)2(NCPh)]+, with the alkynyldithiocarboxylate anions, RCCCS2-, produces the chelate complexes 1 and the mono-coordinated complexes CpRu(PPh3)2(kappaS- S2CCCR) (2). Complexes 2 are converted to 1 in solution so that they were characterized spectroscopically.

The neutral ruthenium complexes Cp?Ru(PR3)2Cl [Cp? = Cp, PR3 = PPh3, PMe3, or 1/2 dppe; Cp? = Cp*, PR3 = PMe3] react with [p-MeOC6H4N2][BF4] in acetone to give new cyclopentadienyl ruthenium aryldiazenido dicationic complexes [Cp?Ru(PR3)2(N2C6H 4OMe)]-[BF4]2 [Cp? = Cp, PR3 = PPh3 (1), PMe3 (2), or 1/2 dppe (3); Cp? = Cp*, PR3 = PMe3 (4)] in good yields. The dicationic complexes 1-3 may also be conveniently isolated in better yield by treatment of the acetonitrile ruthenium complexes [CpRu(PR3)2(NCMe)][BF4] with the arenediazonium salt. When the reaction of Cp?Ru(PPh3)2Cl (Cp? = Cp or Cp*) with [p-MeOC6H4N2][BF4] is carried out in toluene, the product is instead the cyclopentadienyl ruthenium aryldiazenido monocationic complex [Cp?RuCl(PPh3)(N2C6H 4OMe)][BF4] [Cp? = Cp (5) or Cp* (6)]. Further, if the reaction of Cp*Ru(PPh3)2Cl with diazonium salt is carried out in acetone, the binuclear complex [Cp*RuCl(N2C6H4OMe)]2[Cl] 2 (7) can be isolated in low yield in addition to 6. All new complexes 1-7 were fully characterized by NMR, FT-IR, and mass spectroscopies. The structure of [CpRu(PPh3)2(N2C6H 4OMe)][BF4]2·0.93CHCl3 (1· 0.93CHCl3) was determined by single-crystal X-ray diffraction. The structure exhibits a near-linear Ru-N-N-C geometry for the coordinated aryldiazenido group, with the NNC angle having a value of 159, compared to the “sp2” value of approximately 120 commonly exhibited by other “singly bent” aryldiazenido complexes. On the basis of NMR spectroscopic data, 1 reacts with NaBH4 at low temperature to give an arylhydrazido(2-) complex [CpRu(PPh3)2-{NN(H)C6H4OMe}][BF 4], which readily converts to the corresponding aryldiazene complex [CpRu(PPh3)2(NH=NC6H4OMe)][BF 4] by a hydrogen shift; at room temperature, the only product is the hydrido complex CpRuH(PPh3)2.

Cationic ruthenium dihydrogen complexes of the form [(eta-C5H5)Ru(L)(L?)(eta2-H 2)]BF4 (L = CO, L? = PCy3 (1a), PPh3 (2a), PMe2Ph (3a), PMe3 (4a) have been prepared by protonation of the corresponding neutral hydrides. Carbonyl free derivatives such as [(eta-C5H5)Ru(P P?)(eta2-H2)]BF4 (P P? = 1,2-bis(dimethylphosphino)ethane (dmpe) (5a), (1,1-dimethyl-2,2-diphenylphosphino)ethane (dmdppe) (6a), (R)-(+)-1,2-bis(diphenylphosphino)propane ((R)-prophos) (8a), bis(PPh3) (9a)) were similarly prepared. Pentamethylcyclopentadienyl analogues [(eta-C5Me5)Ru(P P?(eta2-H2)]BF4 (P P? = dmdppe (7a), (PPh3J2 (10a)) and [(eta-C5Me5)Ru(CO)(PCy3)(eta 2-H2)]BF4 (11a) have also been prepared. Identification of these species as dihydrogen complexes is based upon observation of substantial H-D coupling (22-32 Hz) in the 1H NMR spectra of the HD analogues, prepared by protonation of the corresponding deuterides. In every case studied in detail, the kinetic product of the protonation reaction is the dihydrogen complex, but an intramolecular isomerization occurs to give variable amounts of the transoid dihydride form at equilibrium. The composition of the equilibrium mixture and the rate at which the equilibrium is obtained depend upon the ligand environment. Facile rotation of the coordinated H2 ligand in the ruthenium complexes is established by the study of chiral complexes. The coordinated H2 in these complexes is substantially activated toward heterolytic cleavage. In the case of 5a, the measured pKa is 17.6 (CH3CN), with the dihydrogen form deprotonated more rapidly than the dihydride.

Reaction of N-(2?-hydroxyphenyl)benzaldimines (abbreviated in general as H2L-R, where R stands for the para-substituent in the benzaldehyde fragment and H stands for the dissociable hydrogen atoms) with [Ru(PPh3)2(CO)2Cl2] affords a family of organoruthenium complexes of the type [Ru(PPh3)2(CO)(L-R)] where the N-(2?-hydroxyphenyl)benzaldimine ligand is coordinated to the metal center as tridentate C,N,O-donor. Structure of a representative complex has been determined by X-ray crystallography. All the [Ru(PPh3)2(CO)(L-R)] complexes are diamagnetic, and show characteristic 1H NMR signals and moderately intense MLCT transitions in the visible region. Cyclic voltammetry of the [Ru(PPh3)2(CO)(L-R)] complexes shows a reversible Ru(II)-Ru(III) oxidation within 0.38-0.68 V versus SCE, followed by an irreversible oxidation of the coordinated benzaldimine ligand within 1.09-1.27 V versus SCE. An irreversible reduction of the coordinated benzaldimine ligand is also observed near -1.1 V versus SCE. Potential of the Ru(II)-Ru(III) oxidation is observed to be sensitive to the nature of para-substituent R.

Reactions between HC?CC?CSiMe3 and several ruthenium halide precursors have given the complexes Ru(C?CC?CSiMe 3)(L2) Cp? [Cp? = Cp, L = CO (1), PPh 3 (2); Cp? = Cp*, L2 = dppe (3)]. Proto-desilylation of 2 and 3 have given unsubstituted buta-1,3-diyn-1-y1 complexes Ru(C?CC?CH)(L2) Cp? [Cp? = Cp, L = PPh3 (5); Cp? = Cp*, L2 = dppe (6)]. Replacement of H in 5 or 6 with Au(PR3) groups was achieved in reactions with AuCl(PR3) in the presence of KN(SiMe3) 2 to give Ru(C?CC?CAu(PR3)}(L 2)Cp? [Cp? = Cp, L = PPh3, R = Ph (7); Cp? = Cp*, L2 = dppe, R = Ph (8), tol (9)]. The asymmetrically end-capped {Cp(Ph3P)2Ru} C?CC?C{Ru(dppe)Cp*} (10) was obtained from Ru(C?CC?CH)(dppe)Cp? and RuCl(PPh3)2Cp. Single-crystal X-ray structural determinations of 1-3 and 6-9 are reported, with a comparative determination of the structure of Fe(C?CC?CSiMe 3)(dppe)Cp? (4), and those of a fifth polymorph of {Ru(PPh 3)2Cp}2(muC?CC?C) (12), and {Ru(dppe)Cp}2(mu-C?CC?C) (13).

A series of half-sandwich bis(phosphine) ruthenium acetylide complexes [Ru(C{triple bond, long}CAr)(L2)Cp?] (Ar = phenyl, p-tolyl, 1-naphthyl, 9-anthryl; L2 = (PPh3)2, Cp? = Cp; L2 = dppe; Cp? = Cp*) have been examined using electrochemical and spectroelectrochemical methods. One-electron oxidation of these complexes gave the corresponding radical cations [Ru(C{triple bond, long}CAr)(L2)Cp?]+. Those cations based on Ru(dppe)Cp*, or which feature a para-tolyl acetylide substituent, are more chemically robust than examples featuring the Ru(PPh3)2Cp moiety, permitting good quality UV-Vis-NIR and IR spectroscopic data to be obtained using spectroelectrochemical methods. On the basis of TD DFT calculations, the low energy (NIR) absorption bands in the experimental electronic spectra for most of these radical cations are assigned to transitions between the beta-HOSO and beta-LUSO, both of which have appreciable metal d and ethynyl pi character. However, the large contribution from the anthryl moiety to the frontier orbitals of [Ru(C{triple bond, long}CC14H9)(L2)Cp?]+ suggests compounds containing this moiety should be described as metal-stabilised anthryl radical cations.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 32993-05-8, you can also check out more blogs about32993-05-8

We report an asymmetric, catalytic transannular aldolization that provides polycyclic products useful for natural product synthesis. We found that a proline-derivative catalyzes the transannular aldol reaction of 1,4-cyclooctanediones to the corresponding cyclic beta-hydroxy ketones in good yields and with high enantioselectivities. The utility of our reaction has been demonstrated in a total synthesis of (+)-hirustene. Copyright
