Abstract

A less expensive and more environmentally friendly Zn(OTf)2-catalyzed dehydrative coupling reaction of propargyl alcohols with diarylphosphine oxides is reported. The reaction takes place under mild and solvent free conditions, and features a high regioselectivity to provide an effective method for the synthesis of some diarylphosphinyl allenes in moderate to high yields.
