Bis(phenyliodonium) diyne triflates 8–10 were prepared by the reaction of the corresponding tributyltin substituted diacetylenes 4–6 with cyanophenyliodonium triflate 7 in 78–93% yields as relatively stable microcrystalline solids. They were characterized by multinuclear NMR, IR, and analytical data. Iodonium salts 8–10 reacted with triphenylphosphine under mild conditions with the loss of iodobenzene giving bisphosphonium salts 11,12 in high yields.
