Bis(phenyliodonium) diyne triflates PhIC.tplbond.C(p-C6H4)nC.tplbond.CIPh.cntdot.20Tf and PhIC.tplbond.C(CH2)nC.tplbond.CIPh.cntdot.20Tf: preparation, characterization, and reaction with triphenylphosphine
摘要:
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.
