Synthesis of alkylbismuths by regiodivergent carbobismuthination of simple alkenes

Abstract

Switchable regioselectivity: This study represents the first carbobismuthination of alkenes achieved by the treatment of an alkene with a bismuth halide and a ketene silyl acetal. This reaction is particularly noteworthy in that a change in the type of halogen on a bismuth atom very easily switched the regioselectivity.

Keywords: alkenes; bismuth; carbobismuthination; ketene silyl acetal; synthetic methods.
