Geminal Difunctionalization of Alkenylidene-Type Carbenoids by Using Interelement Compounds

Geminal Difunctionalization of Alkenylidene-Type Carbenoids by Using Interelement Compounds

A 1,2‐migration of a boryl or silyl group with inversion of configuration occurs in the reaction of alkylidene‐type lithium carbenoids with diboron or silylborane derivatives to give the corresponding 1,1‐diboryl‐ or 1‐boryl‐1‐silylalkenes in good yields (see scheme).
