K2PtCl4/AgOTf as a highly active catalyst for hydroarylation of propiolic acids with arenes
A new and efficient K2PtCl4/AgOTf catalyst for the hydroarylation of propiolic acid was found. The hydroarylation of propiolic acids gave predominantly (Z)-cinnamic acid derivatives in high yields. The K2PtCl4/AgOTf catalyst showed a high activity to less reactive benzene.
