Recent Advances in the Synthesis and the Reactivity of 2-Phosphaethynolate Anion

Since Becker and co-workers isolated the 2-phosphaethynolate anion (P≡C-O -) in 1992, the synthesis of 2-phosphaethynolate anion and its utilizations in the synthesis of phosphorus-containing organic compounds and heterocycles have been gained much attentions.This review mainly summarizes the recently reported methods for the synthesis of 2-phosphaethynolate anions and its utilizations in the synthesis of organophosphorus compounds containing their versatility, substrate scope and limitation.
