Synthesis of Alkylbismuths by Regiodivergent Carbobismuthination of Simple Alkenes

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...

Zusammenfassung: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 (see scheme).
