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. 32993-05-8, Name is Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II), molecular formula is C41H35ClP2Ru. In a Article，once mentioned of 32993-05-8, Product Details of 32993-05-8
Reactions of the ruthenium complex [Ru]Cl ([Ru]=Cp(PPh3)2Ru; Cp=eta5-C5H5) with several aryl propargyl acetates, each with an ortho-substituted chain of various length containing an epoxide on the aromatic ring and with or without methyl substitutents on the epoxide ring, bring about novel cyclizations. The cyclization reactions of HC?CCH(OAc)(C6H4)CH2(RC2H2O) (R=H, 6 a; R=CH3, 6 b, where RC2H2O is an epoxide ring) in MeOH give the vinylidene complexes 5 a?b, respectively, each with the Cbeta integrated into a tetrahydro-5H-benzo[7]annulen-6-ol ring. A C?C bond formation takes place between the propargyl acetate and the less substituted carbon of the epoxide ring. Further cyclizations of 5 a?b induced by HBF4 give the corresponding vinylidene complexes 8 a?b each with a new 8-oxabicyclo-[3.2.1]octane ring by removal of a methanol molecule in high yield. For similar aryl propargyl acetates with a shorter epoxide chain, the cyclization gives a mixture of a vinylidene complex with a tetrahydronaphthalen-1-ol ring and a carbene complex with a tricyclic indeno-furan ring. For the cyclization of 18, with a longer epoxide chain, opening of the epoxide is required to afford the vicinal bromohydrin 22, then tandem cyclization occurs in one pot. Products are characterized by spectroscopic methods as well as by XRD analysis.
