Synthesis of (1-silyl)allylboronates by KOtBu-catalyzed ring-opening gem-silylborylation of cyclopropenes

Abstract

A KOtBu-catalyzed ring-opening gem-silylborylation of cyclopropenes with silylboronates has been developed for the synthesis of (1-silyl)allylboronates, a useful class of compounds in organic synthesis. The reaction proceeds with high selectivity under mild conditions, and the reaction mechanism has been theoretically investigated using DFT calculations.
