Book excerpt: This handbook provides an up-to-date account of hydrosilylation reactions and the directions in which synthetic and mechanistic studies as well as practical applications of these processes are proceeding. The book consists of two parts: the first is descriptive, presenting the catalytic, mechanistic, structural and synthetic aspects of hydrosilylation, as well as its application in organic and organosilicon chemistry. The second part, presented in tabular form sets out encyclopedic information concerning reaction conditions taken from more than 2000 papers and patents in the period 1965 - 1990.
