摘要

Alkynyl (pheny1) iodonium tosylates with long alkoxy chains, such as (octy1oxy)-,(decyloxyl- ,(dodecy1oxy)-, and (tetradecyloxy) phenyl, were prepared by reaction of the corresponding alkynes with hydroxy (tosy1oxy) iodobenzene. The alkynyliodonium tosylates were allowed to react with alkynylcopper reagents (p-RC6H&W) zCu (CN) Li2, where R= MeO, Me, H, Br, CN, and NOz. The coupling reaction proceeded under mild conditions to provide ...
