REACTIONS OF A DICHLOROCARBENE-RUTHENIUM COMPLEX, RuCl2(CCl2)(CO)(PPh3)2

The dichlorocarbene ligand, in the new complex RuCl2(CCl2)(CO)(PPh3)2, readily undergoes substitution reactions in which the integrity of the metal-carbon bond is maintained.Reactions with species H2X (X=O, S, Se) give chalcocarbonyl complexes RuCl2(CX)(CO)(PPh3)2 while RXH (X=O, S) give new carbene complexes RuCl2(CO)(PPh3)2.Ammonia reacts to give a cyanide-containing complex, RuCl(CN)(CO)(NH3)(PPh3)2, and primary amines, an isocyanide complex, or in the case of certain primary diamines cyclic carbene complexes.RuCl2(CNNMe2)(CO)(PPh3)2 is formed in the reaction with N,N-dimethylhydrazine.Secondary amines, R2NH, react to give chloroaminocarbene complexes, RuCl2(CO)(PPh3)2.

Kinetic selectivity of olefin metathesis catalysts bearing cyclic (alkyl)(amino)carbenes

The evaluation of ruthenium olefin metathesis catalysts 4-6 bearing cyclic (alkyl)(amino)carbenes (CAACs) in the cross-metathesis of cis-1,4-diacetoxy-2- butene (7) with allylbenzene (8) and the ethenolysis of methyl oleate (11) is reported. Relative to most NHC-substituted complexes, CAAC-substituted catalysts exhibit lower E/Z ratios (3:1 at 70% conversion) in the cross-metathesis of 7 and 8. Additionally, complexes 4-6 demonstrate good selectivity for the formation of terminal olefins versus internal olefins in the ethenolysis of 11. Indeed, complex 6 achieved 35 000 TONs, the highest recorded to date. CAAC-substituted complexes exhibit markedly different kinetic selectivity than most NHC-substituted complexes.

Reactions of the Lithiated Diphosphine tBu2P?P(SiMe3)Li with [(eta6-C6H6)RuCl2]2in the Presence of Tertiary Phosphines

tBu2P?P(SiMe3)Li reacted with [(eta6-C6H6)RuCl2]2at ?40 C in the presence of PR3(PR3= PEt3, PEt2Ph, PEtPh2) by the nucleophilic addition of the tBu2P?P(SiMe3) moiety to the benzene ring to yield solely the complexes [(R3P)2Ru(Cl){eta5-C6H6(Me3SiP?PtBu2)}] (1). These products decomposed slowly at ambient temperature to yield benzene, Ru clusters, and small amounts of the dinuclear ruthenium complexes [{(R3P)2Ru}2(mu,eta2:2-P2)2Ru(PR3)2] (Ru?Ru) (6). Single-crystal X-ray diffraction studies of [(PhEt2P)2Ru(Cl){eta5-C6H6(Me3SiP?PtBu2)}] (1b) and [(Ph2EtP)2Ru(Cl){eta5-C6H6(Me3SiP?PtBu2)}] (1c) revealed that the addition of the tBu2P?P(SiMe3) group occurred through an exo pathway. Complex 6a (R = Et) displays a planar rectangular P4system consisting of two P2units and a Ru?Ru distance that lies in the range of a single bond.

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: 37366-09-9, you can also check out more blogs about37366-09-9

Nitrosyl ruthenium complexes with general formula [RuCl3(NO)(P-P)] (P-P = {PPh2(CH2)nPPh2}, n = 1-3 and {PPh2-CH = CH-PPh2}). X-ray structure of [RuCl3(NO){PPh2(CH2)3PPh 2}]

Ruthenium(II) complexes with general formula [RuCl3(NO)(P-P)] were obtained in the solid state, where P-P = PPh2(CH2)nPPh2 (n = 1-3) and PPh2-CH = CH-PPh2. The 31P NMR spectra of these compounds measured in CH2Cl2 showed only singlets, consistent with a fac configuration containing two equivalent phosphorus atoms. However the X-ray diffraction data show that the [RuCl3(NO){PPh2(CH2)3PPh 2}] complex crystallizes in a mer configuration, where one of the phosphorus atoms is trans to the NO group, in a slightly distorted octahedral geometry.

Near-IR phosphorescent ruthenium(II) and iridium(III) perylene bisimide metal complexes

The phosphorescence emission of perylene bisimide derivatives has been rarely reported. Two novel ruthenium(II) and iridium(III) complexes of an azabenz-annulated perylene bisimide (ab-PBI), [Ru(bpy)2(ab-PBI)][PF6]2 1 and [CpIr-(ab-PBI)Cl]PF6 2 are now presented that both show NIR phosphorescence between 750-1000 nm in solution at room temperature. For an NIR emitter, the ruthenium complex 1 displays an unusually high quantum yield (Fp) of 11% with a lifetime (tp) of 4.2 ms, while iridium complex 2 exhibits Fp < 1% and tp =33 ms. 1 and 2 are the first PBI-metal complexes in which the spin-orbit coupling is strong enough to facilitate not only the Sn?Tn intersystem crossing of the PBI dye, but also the radiative T1?S0 transition, that is, phosphorescence.

Synthesis and characterization of organic dyes containing 4,5-diazafluorene as efficient sensitizers for dye-sensitized solar cells

Two dyes which are 4,5-diazafluoren-9-one-derived diimine ligands and their corresponding Ru(II) bipyridine complexes were synthesized. The structures of all compounds were determined by FTIR, UV?Vis, 1H-NMR, 1C-NMR, and MS spectroscopic data. The photovoltaic and electrochemical properties of these compounds were investigated and the applicability in DSSCs as photosensitizers was studied. The photovoltaic cell efficiencies (PCE) of the devices were 0.36?1.26% under simulated AM 1.5 solar irradiation of 100?mW/cm2, and the highest open-circuit voltage (Voc) reached 0.34?V.

Study of half-sandwich platinum group metal complexes bearing dpt-NH2 ligand

A quite general approach for the preparation of eta5-and eta6-cyclichydrocarbon platinum group metal complexes is reported. The dinuclear arene ruthenium complexes [(eta6-arene)Ru(mu-Cl)Cl]2 (arene = C6H6, C10H14 and C6Me6) and eta5-pentamethylcyclopentadienyl rhodium and iridium complexes [(eta6-C5Me5)M(mu-Cl)Cl]2 (M = Rh, Ir) react with 2 equiv. of 4-amino-3,5-di-pyridyltriazole (dpt-NH2) in presence of NH4PF6 to afford the corresponding mononuclear complexes of the type [(eta6-arene)Ru(dpt-NH2)Cl]PF6 {arene = C10H14 (1), C6H6 (2) and C6Me6 (3)} and [(eta6-C5Me5)M(dpt-NH2)Cl]PF6 {M = Rh (4), Ir (5)}. However, the mononuclear eta5-cyclopentadienyl analogues such as [(eta5-C5H5)Ru(PPh3)2Cl], [(eta5-C5H5)Os(PPh3)2Br], [(eta5-C5Me5)Ru(PPh3)2Cl] and [(eta5-C9H7)Ru(PPh3)2Cl] complexes react in presence of 1 equiv. of dpt-NH2 and 1 equiv. of NH4PF6 in methanol yielded mononuclear complexes [(eta5-C5H5)Ru(PPh3)(dpt-NH2)]PF6 (6), [(eta5-C5H5)Os(PPh3)(dpt-NH2)]PF6 (7), [(eta5-C5Me5)Ru(PPh3)(dpt-NH2)]PF6 (8) and [(eta5-C9H7)Ru(PPh3)(dpt-NH2)]PF6 (9), respectively. These compounds have been totally characterized by IR, NMR and mass spectrometry. The molecular structures of 4 and 6 have been established by single crystal X-ray diffraction and some of the representative complexes have also been studied by UV-Vis spectroscopy.
