摘要：

A variety of functionalized alkynyliodonium salts 4a-o are prepared in good yields via a novel iodonium-transfer process between the appropriate alkynylstannanes 2 and PhI+CN.-OTf. The electron-deficient acetylenes 4 readily undergo cycloaddition reactions at room temperature with endocyclic. exocyclic,and acyclic 1,3-dienes to afford functionalized vinyliodonium adducts of type 5, 6, 7, and 9.
