Nucleophiles allyl-silicon bonds activated

At the same time, synthetic methods using the efficacy of nucleophilic agents in the activation of various silicon-element bonds, such as Si-H, Si-O, Si-N, and Si-C, were developed. The activation of these bonds was used as a tool for reduction of carbonyl compounds (271-273), Michael condensations (274,275), and formation of heterodienes by cleavage of the Si-N bond (276). The activation of the Si-C bond has received particular attention, as illustrated by the cleavage of the Si-allyl bond (277) and the use of pentafluorosilicates as synthetic intermediates (278).
