Abstract
A detailed mechanism of the exemplified hydrosilylation of 1-hexene by triethoxysilane catalyzed by [RhCl(COD)(phosphine)] (1), where phosphine is PPh3 or 1/2 bis(diphenylphosphinoethyl)tetramethyldisiloxane has been presented. The mechanism has been deduced from the results of kinetic studies (by spectrophotometry and GLC) of most of the individual consecutive-competitive steps of the reaction. Individual rate constants have been determined from the reactions of the initial complex 1, described previously as, and of the isolated intermediates with various substrates and oxidants. It has been concluded that the hydrosilylation consists of two distinct stages, the activation of the rhodium precursor by initiating the active intermediates, followed by a very much faster but usual catalytic cycle of hydrosilylation. © 1990.
