Alkynylsilanes reacted with aryl or alkenyl triflates in the presence of 5 mol% of Pd(PPh3)4 and 10 mol% of CuCl in DMF to give the corresponding cross-coupling, namely "sila"-Sonogashira-Hagihara coupling, products in good to excellent yields. The present reaction is highly effective for one-pot synthesis of unsymmetrical diarylacetylenes.
