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.
