Kinetic studies of reactions of organosilylenes: what have they taught us?

Becerra, R. and Walsh, R. (2010) Kinetic studies of reactions of organosilylenes: what have they taught us? Dalton Transactions, 39 (39). pp. 9217-9228. ISSN 1364-5447 doi: 10.1039/c0dt00198h

Abstract/Summary

Rate constants for bimolecular reactions, obtained through time-resolved kinetic studies both in the gas and liquid phases are reviewed. Data for reactions of MeSiH, PhSiH, ClSiH, SiCl2, SiMe2, MeSiPh, SiPh2 and SiMes(2) are covered. Where possible, substituent effects relative to SiH2 have been obtained. These demonstrate widely varying effects between different types of reaction, which aids mechanistic understanding. Reactivities are high for all silylenes, but substituents can reduce them by both electronic and steric effects. The gas and liquid phase data (mainly for SiMe2) are compared and appear to be reasonably consistent. This review, although detailed, is not comprehensive.
