Abstract
A γ,δ-unsaturated carboxylic acid silyl ester is prepared by reacting an α,β-unsaturated carboxylic acid ester with a hydrosilane or hydrosiloxane in the presence of tris(pentafluorophenyl)borane. γ,δ-Unsaturated carboxylic acid derivatives are readily prepared through fewer steps and in high yields.
