Abstract
The first phosphinodifluoroalkylation of alkynes is achieved and the simultaneous addition of both difluoromethylene and phosphinoyl groups across the alkynes with high regio- and stereoselectivity is of great significance. By using palladium(II) chloride as a catalyst and Xantphos as a ligand, the reaction of P(O)H compounds, alkynes, and ethyl difluoroiodoacetate proceeds with moderate to high yields, and provides an attractive approach for the construction of (E)-γ,γ-difluoroalkenylphosphine oxides.
