Abstract

Three become one: The first carbobismuthination of alkynes has been accomplished by the simple reaction of an alkyne, BiBr3, and a ketene silyl acetal to produce an alkenylbismuth with high stereo- and regioselectivity (see scheme). X-ray crystallographic analysis of the alkenylbismuth product and control experiments using α-bismuthino ester revealed the reaction mechanism.
