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. 301224-40-8, Name is (1,3-Dimesitylimidazolidin-2-ylidene)(2-isopropoxybenzylidene)ruthenium(VI) chloride, molecular formula is C31H38Cl2N2ORu. In a Article，once mentioned of 301224-40-8, Quality Control of: (1,3-Dimesitylimidazolidin-2-ylidene)(2-isopropoxybenzylidene)ruthenium(VI) chloride
The reaction of a ruthenium carbide complex RuCl2(C:) (PCy 3)2 with [H(Et2O)x] +[BF4]- at a molar ratio of 1:2 produced a two-core ruthenium carbene complex {[RuCl(CHPCy3)(PCy 3)]2(mu-Cl)3}+·[BF 4]- (8) in the form of a yellow-green crystalline solid. After a ligand exchange reaction of 8 with LiBr, a bromide ruthenium carbene complex {[RuBr(CHPCy3)(PCy3)]2(mu-Cl) 3}+·[BF4]- (9) was obtained as a crystalline solid. Catalytic studies showed that both 8 and 9 are selective catalysts for ring closing metathesis of unsubstituted terminal dienes. More importantly, no isomerized byproduct was observed when 8, or 9 was used as the catalyst at an elevated temperature (137 C), indicating that both 8 and 9 are chemo-selective catalysts for ring closing metathesis reactions.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.Quality Control of: (1,3-Dimesitylimidazolidin-2-ylidene)(2-isopropoxybenzylidene)ruthenium(VI) chloride, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 301224-40-8, in my other articles.
