Reactions of ruthenium(II) tris(pyrazolyl)borate and tris(pyrazolyl)methane complexes with diphenylvinylphosphine and 3,4-dimethyl-1-phenylphosphole

Several new ruthenium(II) tris(pyrazolyl)borate and tris(pyrazolyl)methane complexes containing diphenylvinylphosphine (DPVP), 3,4-dimethyl-1-phenylphosphole (DMPP) and 1,2-bis (diphenylphosphino) ethane (dppe), namely: (Tp)Ru (DPVP) (CH3CN)Cl; (Tp)Ru (DPVP)2Cl; (Tp)Ru (DPVP) (DMPP) [4+2]Cl; [(Tp)Ru (DPVP)2 (CH3CN)]PF6; (Tp)Ru (DMPP)2 [4+2]Cl; [(Tpm)Ru (DPVP)2 Cl]PF6; [(Tpm)Ru(dppe)Cl]PF6; [(Tpm)Ru(DMPP)2 [4+2]Cl]PF6 and [(Tp)Ru (dppe) (Me2CO)]PF6 have been prepared, characterized and their reaction chemistry studied. Characterization includes infrared spectroscopy, 1H-, 13C{1H}- and 31P{1H}-NMR spectroscopy and in several cases X-ray crystallography.
