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. 172222-30-9, Name is Benzylidenebis(tricyclohexylphosphine)dichlororuthenium, molecular formula is C43H72Cl2P2Ru. In a Article，once mentioned of 172222-30-9, name: Benzylidenebis(tricyclohexylphosphine)dichlororuthenium
Treatment of the hydrido(dihydrogen) compound [RuHCl(H2) (PCy3)2] 1 with alkynes RC?CH (R = H, Ph) afforded the hydrido(vinylidene) complexes [RuHCl(=C=CHR)(PCy3)2] 2, 3 which react with HCl or [HPCy3]Cl to give the corresponding Grubbs-type ruthenium carbenes [RuCl2(=CHCH2R)(PCy 3)2] 4, 5. The reaction of 2 (R = H) with DCl, or D 2O in the presence of chloride sources, led to the formation of [RuCl2(=CHCH2D)(PCy3)2] 4-d 1. Based on these observations, a one-pot synthesis of compounds 4 and 5 was developed using RuCl3·3H2O as the starting material. The hydrido(vinylidene) derivative 2 reacted with CF 3CO2H and HCN at low temperatures to yield the carbene complexes [RuCl(X)(=CHCH3)(PCy3)2] 6,7, of which 7 (X = CN) was characterized crystallographically. Salt metathesis of 2 with CF3CO2K and KI led to the formation of [RuH(X)(=C=CH2)(PCy3)2] 8, 9. The bis(trifluoracetato) and the diiodo compounds [RuX2(=CHCH 3)(PCy3)2] 10,11 as well as the new phosphine P(thp)3 12 (thp = 4-tetrahydropyranyl) and the corresponding complex [RuCl2(=CHCH3){P(thp)3}2] 14 were also prepared. The catalytic activity of the ruthenium carbenes 4-7, 10, 11 and 14 in the olefin cross-metathesis of cyclopentene and allyl alcohol was investigated. The Royal Society of Chemistry 2005.
