Abstract
1-Alkynyl(phenyl)-lambda 3-iodanes undergo selective transfer of the alkynyl groups over the phenyl group onto diphenyl chalcogens. Exposure of 1-alkynyl(phenyl)-lambda 3-iodanes to diphenyl chalcogens (S, Se, and Te) in dichloromethane or 1,2-dichloroethane affords 1-alkynyl(diphenyl)sulfonium, -selenonium, and -telluronium salts in high yields.
摘要
1-炔基（苯基）-λ³-碘烷能使炔基选择性地从苯基转移到二苯基硫属元素化物上。在二氯甲烷或1,2-二氯乙烷中，将1-炔基（苯基）-λ³-碘烷与二苯基硫属元素化物（硫、硒和碲）反应，可高产率地得到1-炔基（二苯基）锍盐、硒鎓盐和碲鎓盐。
