The reaction of diphenylketene with terminal acetylenes catalyzed by tetrakis-(triphenylphosphine)palladium gave disubstituted acetylenes in high yields. Ketenes are known to undergo a variety of charactaristic reactions and to form complexes with transition metals. ') A currently important area in
Palladium-Catalyzed Condensation of Aryl Iodides and Diaryliodonium Salts with Terminal Acetylenes in Aqueous Media. -Aryl iodides as well as diaryliodonium salts smoothly react with terminal acetylenes in aqueous solutions containing catalytic amounts of PdCl2(PPh3)2 and CuI to furnish the corresp
