A New Hydrosilylation Mechanism - New Preparative Opportunities

摘要

The Si-H bond is polar, long, and weak, and therefore, very reactive. Its addition across a double bond (hydrosilylation) is an important reaction not only in organosilicon chemistry but also in organic synthesis and dendrimer and polymer chemistry. It is a catalytic reaction for which a large variety of catalysts is available. They control the regio- and stereoselectivity including the enantioselectivity. Most of these catalysts operate according to the well-established Chalk-Harrod mechanism or one of its variants resulting in the cis addition of a Si-H bond to an alkene.
