摘要
芳基乙炔与羟基对甲苯磺酰氧基碘苯在分子筛催化下反应，生成苯乙炔基对甲苯磺酰氧基碘苯，产率４４％～４９％。１－三甲基硅基炔与亚碘酰苯在三氟化硼乙醚溶液中反应，经对甲苯磺酸钠水溶液处理后，得炔基对甲苯磺酰氧基碘苯，产率４６％～６５％。
Treatment of arylethynes with hydroxy (tosyloxyiodo) benzene in present of desiccant afforded arylethylnylphenyliodonium tosylates in 44% - 49% yield. Treatment of 1-(trimethylsily )-1-alkynes with iodobenzene in present of BF3. OEt2 afforded a yellow solution, which react with sodium tosylate to give alkynylphenyliodonium tosylates in 46% - 65% yield.
