92361-49-4, Name is Chloro(pentamethylcyclopentadienyl)bis(triphenylphosphine)ruthenium(II), molecular formula is C46H45ClP2Ru, belongs to ruthenium-catalysts compound, is a common compound. In a patnet, once mentioned the new application about 92361-49-4, Synthetic Route of 92361-49-4
A series of Cp’Ru(PR3)(PPh3)Cl complexes, where Cp? = Cp*, Dp, Ind, Cp, Tp and PR3 = PTA, PMe3, PPh3, have been used to catalyze the atom transfer radical addition (ATRA) of various chloro substrates (CC14, CHC1 3, and TsCl) to styrene and/or hexene. The complexes Cp *Ru(PTA)(PPh3)Cl, Cp*Ru(PMe 3)(PPh3)Cl, DpRu(PMe3)(PPh3)Cl, and TpRu(PMe3)(PPh3)Cl have been synthesized by ligand exchange reactions with Cp?Ru(PPh3)2Cl and characterized by NMR spectroscopy and X-ray crystallography. An alternative synthesis for CpRu(PMe3)(PPh3)Cl and the solid-state structure of the previously reported complex IndRu(PMe3)(PPh 3)Cl are also described. Among the ruthenium(II) complexes studied, Cp*Ru(PTA)(PPh3)Cl and Cp *Ru(PMe3)(PPh3)Cl were very active at 60 C with TOF values of 1060 and 933 h-1, respectively; Cp *Ru(PPh3)2Cl was the most active for the addition of CCI4 to styrene with a TOF > 960 h-1 at room temperature. Total turnovers (TTO) in excess of 80000 for the addition of CC14 to hexene were obtained for the Cp* complexes, making these complexes the most active and robust catalysts for ATRA reported to date.
