Abstract

Efficient Cs2CO3-promoted phosphorylations or phosphinylations of various 1,1-dibromo-1-alkenes with readily available trialkyl phosphites, ethyl diphenylphosphinite, or diethyl phenylphosphonite under metal-free conditions provide valuable alkynylphosphonates, -phosphinates, and -phosphine oxides in very good yields.
