A study was performed on the metathesis of electron-rich olefins. The structure and reactivity of electron-rich carbene complexes were also investigated. It was found that the complexes coordinated with an N-heterocyclic carbene ligand displayed enhanced activities in olefin metathesis and were thermally more stable than their bis(phosphine) analogues.

Cationic ruthenium sulfine complexes [CpRu(PR?3)2(O=S=CHR)]PF6 have been obtained by a variety of methods. Oxidation of the thioaldehyde complexes [CpRu(PR?3)2(S=CHR)]PF6 with either 2-tosyl-3-phenyl-oxaziridine (PR?3 = PMe3) or magnesium-monoperoxyphthalate (PR?3 = 1/2 dppm) gave complexes of arylsulfines (R = Ph, 3-C6H4F, 4-C6H4Cl, 4-C6H4OMe) selectively in their thermodynamically less stable E form. Siloxane elimination from the sulfinato complexes [CpRu(PMe3)2(SO2CHRSiMe3)] yielded complexes of aliphatic sulfines, [CpRn(PMe3)2(O=S=CHR)]PF6 (R = H, Me). Treatment of [CpRu(dppm)(SO2CH2R)] with acetyl chloride led to an oxygen redistribution giving complexes of thioaldehydes [CpRu(dppm)(eta2-S=CH2)]PF6 and [CpRu(dppm)(eta1-S=CHR)]PF6 (R = Ph, 4-C6H4Cl). The structure of the latter was determined by X-ray crystallography. The loss of oxygen can be suppressed by performing the acylation-elimination sequence in the presence of poly-(4-vinylpyridine). This provided a selective access to complexes of Z-sulfines, [CpRu(PMe3)2(O=S=CHR)]PF6 (R = Ph, 4-C6H4Cl) and [CpRu(dppm)(O=S=CHR)]PF6 (R = Ph, 4-C6H4Cl, COOEt, Cl). Complexes of the parent sulfine O=S=CH2 were also obtained by SO transfer to the methylene complex [CpRu(PMe3)2(CH2)]PF6 and methylene transfer to the sulfur monoxide complex [Cp*Ru(PMe3)2 (SO)]PF6. Most of the new sulfine complexes exhibit dynamic behaviour in solution, i. e. ligand rotation, ligand inversion, and eta2/etaI hapticity change. O-Alkylation provided the dicationic complex [CpRu(PMe3)2 (EtO-S=CHMe)](PF6)2, and S-oxidation gave the sulfene complexes [(C5R5)Ru(PMe3)2 (O2S=CH2)]PF6 (R = H, Me).

A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), molecular formula is C20H16Cl2N4Ru. In a Article，once mentioned of 15746-57-3, Application In Synthesis of Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II)

A comparative photophysical study has been carried out on the complexes (bpy)2Ru(MQ+)2/4+ and (bpy)2Ru(bpy-py-Me+)3+ (1 and 2, respectively, where bpy= 2,2′-bipyridine, MQ+ is N-methyl-4,4′-bipyridinium and bpy-py-Me+ is 4-(N-methyl-4-pyridyl)-2,2′-bipyridine). In addition, the X-ray crystal structure of 2 is reported. As noted previously by Meyer and co-workers, complex 1 features strong photoluminescence from the Ru ? bpy metal-to-ligand charge transfer (MLCT) state at 80 K in an ethanol-methanol glass, but the emission is quenched at the solvent glass-to-fluid transition temperature due to intramolecular ligand-to-ligand charge transfer to produce the Ru ? MQ+ MLCT state: [(bpy)(bpy-·)Ru(III)(MQ+)2](4+*) ? (bpy)2Ru(III)(MQ·)(MQ+)](4+*). The existence of the Ru ? MQ+ MLCT state is confirmed in the present study by laser flash photolysis of 1 at 160 K which provides evidence for the reduced monoquat ligand, MQ·. The photophysics of the new complex 2 at temperatures ranging from 80 to 300 K is dominated by a the low-lying Ru ? bpy-py-Me+ MLCT state. Luminescence is observed from this state in an ethanol-methanol glass at 80 K as well as at temperatures above the solvent glass-to-fluid transition. The photoluminescence of 2 undergoes a large thermally-induced Stokes shift as the temperature is raised through the solvent glass-to-fluid transition region. The large Stokes shift is ascribed to solvent relaxation as well as relaxation with respect to a low-frequency inner sphere mode that consists of rotation around the C-C bond between the bpy and N-methylpyridinium rings in the bpy-py-Me+ acceptor ligand. Temperature dependent emission lifetime studies indicate that 2 features a dynamic anti-Stokes shift in the emission at T ? 110 K and a dynamic Stokes shift for T > 110 K.

An efficient double bond migration-ring closing metathesis reaction leading to cycloheptene derivatives is observed when specific sterically congested 1,9-dienes are treated with the Grubbs’ imidazolidene ruthenium catalyst. The simultaneous use of the Grubbs’ catalyst and RuClH(CO)(PPh3) 3 facilitates the tandem bond migration-metathesis process. RuClH(CO)(PPh3)3 alone is capable of triggering an unactivated double bond migration that may have preparative applications.
