Synthesis and transition metal chemistry of ferrocenylbis(benzo-oxazaphosphininone)

The new ferrocenylbis(oxazaphosphininone), [Fe{C5H4P(OC6H4)(CO)N-(C2H4Cl)}2] (1) was synthesized by the reaction of bis(dichlorophosphino)ferrocene with two equivalents of 2(2?-hydroxy)phenyloxazoline in the presence of triethylamine in 83% yield. The reactions of 1 with aq. H2O2 or elemental sulfur afforded bis-chalcogenides [Fe{C5H4P(E)(OC6H4)(CO)N(C2H4Cl)}2] (2 E = O, 3 E = S). Treatment of 1 with [M(CO)4(C5H11N)2] (M = Mo, W), [RuCp(PPh3)2Cl] and [M(COD)Cl2] (M = Pd, Pt) afforded the chelate complexes [Fe{C5H4P(OC6H4)(CO)N(C2H4Cl)}2{M(CO)4}] (4 M = Mo, 5 M = W), [Fe{C5H4P(OC6H4)(CO)N(C2H4Cl)}2{RuCp(Cl)}] (7) and [Fe{C5H4P(OC6H4) (CO)N(C2H4Cl)}2{MCl2}] (8 M = Pd, 9 M = Pt), whereas the reaction of 1 with [Ru(eta6-p-cymene)Cl2]2, yielded a bimetallic complex [Fe{C5H4P(OC6H4)(CO)N(C2H4Cl)}2{RuCl2(eta6-p-cymene)}2] (6). The reaction between 1 and CuX in equimolar ratio also yielded binuclear complexes, [Fe{C5H4P(OC6H4)(CO)N(C2H4Cl)}2{CuX}2] (10 X = Cl, 11 X = Br, 12 X = I).

Synthesis of a ruthenium(II) complex containing an [11]ane-P 2CNHC (NHC = Imidazolidin-2-ylidene) macrocycle

Reaction of [RuCl(Cp)(PPh3)2] with bis[di(2-fluorophenyl)phosphino]benzene, 3, yields complex [RuCl(Cp)(3)], [4]. The chloro ligand in [4] can be exchanged for the 2-azidoethyl isocyanide ligand 2, giving complex [Ru(Cp)(2)(3)]Cl, [5]Cl, which reacts with NH 4BF4 to give [5]BF4. The azido group of the coordinated isocyanide ligand in [5]C1 or [5]BF4 can be reduced with Zn/NH4Cl/H2O to give the complex with the 2-aminoethyl isocyanide ligand. This ligand is not stable but cyclizes by an intramolecular nucleophilic attack of the amino group at the isocyanide carbon atomto give an NH, NH-stabilized NHC ligand in complexes [6]X (X = Cl, [6]C1; X = 0.5 ZnCl 4, [6]2(ZnCl4); X = BF4, [6]BF 4). Deprotonation of the NH,NH-stabilized NHC ligands in cations of type [6]+ leads to an intramolecular nucleophilic attack of the amido nitrogen atoms at the fluorinated phenyl groups of the diphosphine ligand under formation of the complex with the facially coordinated macrocyclic [11]ane-P2CNHC ligand [1]X (X = Cl, [1]Cl; X = 0.5 ZnCl4, [1]2(ZnCl4); X = BF4, [1]BF4). Formation of the macrocycle is facilitated by the steric pressure excerted by the cyclopentadienyl ligand. The molecular structures of [4], [5]BF4, [6]BF4-CH2Cl2, and [1]Cl¡¤CH2Cl2¡¤0.5H2O have been determined by X-ray diffraction.

Pyramidal stability of 16-electron half-sandwich intermediates [CpRu(P-P)]+ with P-P ligands forming four- to six-membered chelate rings

This paper reports the synthesis, isomer separation, and X-ray characterization of the compounds (SRu,Sc)-/(RRU,Sc)- [CpRu(Chairphos)Cl], Chairphos = (S)-1,3-bis(diphenylphosphanyl)butane, and cis-/trans-[CpRu(Dppm-Me)Cl], Dppm-Me = 1,1-bis(diphenylphosphanyl)etnane. The Cl/I exchange reactions proceeded with predominant retention of the metal configuration, accompanied by some inversion, except for rrai-[CpRu(Dppm- Me)Cl], which was stereospecifically converted to trans-[CpRu(Dppm-Me)I]. Temperature-dependent kinetic measurements afforded rates and activation parameters of the Cl/I exchange and epimerization reactions that follow basilica-type energy profiles. Dissociation of CF from [CpRu(Chairphos)Cl] and [CpRu(Dppm-Me)Cl] gives pyramidal intermediates [CpRu(Chairphos)]+ and [CpRu(Dppm-Me)]+, which maintain the metal configuration. The 16-electron intermediates can react with excess I- to form the iodo complexes with retention of the metal configuration, or they can change the metal configuration by pyramidal inversion, leading to formation of iodo complexes with inverted metal configuration. The kinetic measurements show that the pyramidal inversion via planar transition states depends on the P-Ru-P’ angles. It increases with decreasing chelate ring size, because small P-Ru-P’ angles resist planarization in the transition, which requires larger P-Ru-P’ angles.

Poly(alkylidenimine) dendrimers functionalized with the organometallicmoiety [Ru(nu 5-C5H5)(PPh3)2]+ as promising drugs against cisplatin-resistant cancer cells and humanmesenchymal stem cells

Here and for the first time, we show that the organometallic compound [Ru(nu5-C5H5)(PPh3)2Cl] (RuCp) has potential to be used as a metallodrug in anticancer therapy, and further present a new approach for the cellular delivery of the [Ru(nu5-C5H5)(PPh3)2]+ fragment via coordination on the periphery of low-generation poly(alkylidenimine) dendrimers through nitrile terminal groups. Importantly, both the RuCp and the dendrimers functionalized with [Ru(nu5-C5H5)(PPh3)2]+ fragments present remarkable toxicity towards a wide set of cancer cells (Caco-2, MCF-7, CAL-72, and A2780 cells), including cisplatin-resistant human ovarian carcinoma cell lines (A2780cisR cells). Also, RuCp and the prepared metallodendrimers are active against human mesenchymal stem cells (hMSCs), which are often found in the tumor microenvironment where they seem to play a role in tumor progression and drug resistance.

Preparation of diazoalkane complexes of ruthenium and their cyclization reactions with alkenes and alkynes

The diazoalkane complexes [Ru(eta5-C5H 5)(N2CAr1Ar2)(PPh3)(L)]BPh4 (1-5: Ar1 = Ar2 = Ph (a), Ar1 = Ph and Ar2 = p-tolyl (b), Ar1Ar2 = C 12H8 (c), Ar1 = Ph and Ar2 = PhCO (d); L = PPh3 (1), P(OMe)3 (2), P(OEt)3 (3), PPh(OEt)2 (4), ButNC (5)) were prepared by allowing the chloro compounds RuCl(eta5-C5H5)(PPh3)(L) to react with the diazoalkanes Ar1Ar2CN2 in ethanol. Treatment of complexes 1-5 with ethylene (CH2=CH2) under mild conditions (1 atm, room temperature) led not only to the eta2-ethylene complexes [Ru(eta5-C5H5)(eta2-CH 2=CH2)(PPh3)(L)]BPh4 (10-14) but also to dipolar (3 + 2) cycloaddition, affording the 4,5-dihydro-3H-pyrazole derivatives [Ru(eta5-C5H5){eta1- N=NC(Ar1Ar2)CH2CH2}(PPh3)(L)]BPh4 (6-9). Acrylonitrile (CH2=C(H)CN) reacted with diazoalkane complexes 2 and 3 to give the 1H-pyrazoline derivatives [Ru(eta5-C 5H5){eta1-N=C(CN)CH2C(Ar1Ar2)NH} (PPh3)(L)]BPh4 (19, 20). However, reactions with propylene (CH2=C(H)CH3), maleic anhydride (ma, CH=CHCO(O)CO) and dimethyl maleate (dmm, CH3OCOCH=CHOCOCH3) led to the eta2-alkene complexes [Ru(eta5-C5H 5)(eta2-R1CH=CHR2)(PPh3)(L)]BPh4 (17-22). Treatment of the diazoalkane complexes 1 and 2 with acetylene CH?CH under mild conditions (1 atm, room temperature) led to dipolar cycloaddition, affording the 3H-pyrazole complexes [Ru(eta5-C 5H5){eta1-N=NC(Ar1Ar2)CH=CH}(PPh 3){P(OMe)3}]BPh4 (24), whereas reactions with the terminal alkynes PhC?CH and ButC?CH gave the vinylidene derivatives [Ru(eta5-C5H5){=C=C(H) R}(PPh3){P(OMe)3}]BPh4 (25, 26). The alkyl propiolates HC?CCOOR1 (R1 = Me, Et) also reacted with complexes 2 to give the 3H-pyrazole complexes [Ru(eta5-C5H 5){eta1-N=NC(Ar1Ar2)C(COOR1)=CH}(PPh3){P(OMe) 3}]BPh4 (27, 28). The complexes were characterized by spectroscopy and by X-ray crystal structure determinations of [Ru(eta5-C5H5){eta1-N=C(CN) CH2C(Ph)(p-tolyl)NH}(PPh3){P(OMe)3}]BPh 4 (19b), [Ru(eta5-C5H5) {eta2-CH=CHCO(O)CO}(PPh3){P(OMe)3}]BPh 4 (21), and [Ru(eta5-C5H5) {eta1-N=NC(C12H8)CH=CH}(PPh 3){P(OMe)3}]BPh4 (24c).
