and hexane leads to the ortho-metallated phenylacetylide; subsequent addition of methyl iodide, dimethyl disulphide, trimethylchlorosilane, and selenium gives the corresponding ortho-substituted phenylacetylenes and benzoselenophen.
在四氢呋喃和己烷的混合物中,苯基乙炔化锂与BuLi–Bu t OK络合物的反应生成邻金属化的苯基乙炔。随后加入甲基碘,二甲基二硫化物,三甲基氯硅烷和硒,得到相应的邻位取代的苯基乙炔和苯并硒吩。
