The regioselective carboindation of simplealkenes with indium tribromide and ketene silyl acetals was accomplished. Various alkenes such as ethylene, 1-alkenes, and cyclic alkenes were applicable for this reaction system. The alkylindium product from the carboindation of cyclohexene revealed an anti addition mechanism.

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).
