Silver-Mediated Selective Oxidative Cross-Coupling between C–H/P–H: A Strategy to Construct Alkynyl(diaryl)phosphine Oxide

Abstract

A direct oxidative cross-coupling between terminal alkynes and secondary phosphine oxides was developed. This approach provides an efficient way to construct alkynyl di(phenyl) phosphine oxides from basic materials, and in this process, the silver salts act as a key promoter.
