Alkylpotassium-Catalyzed Benzylic C-H Alkylation of Alkylarenes with Alkenes

Abstract

Catalytic benzylic C-H alkylation reactions of alkylarenes with alkenes such as β-substituted styrenes and vinylsilanes have been achieved by utilizing alkylpotassium as a catalyst. Various substituted toluene derivatives can be alkylated under mild reaction conditions to afford the desired functionalized hydrocarbons in moderate to high yields.
