A general and efficient method for the direct alkynylation of trifluoropyruvate and trifluoroacetophenone in water was developed by using AgF and PCy3 as a catalyst. The ligand enhanced the catalyst activity significantly. The reaction in water is comparable to the one carried out in organic solvents.
