An efficient three-component benzoselenophenes formation has been developed from substituted indoles, acetophenones, and selenium powder under metal-free conditions. 2-Aryl indoles played an important role to promote benzoselenophene formation from acetophenone derivatives and selenium powder. One C–C and two C–Se bonds were selectively formed to provide 40 new benzoselenophenes in good yields.
在无金属条件下,由取代的吲哚,苯乙酮和硒粉开发了一种有效的三组分苯并硒吩形成方法。2-芳基吲哚对促进苯乙酮衍生物和硒粉中苯并硒吩的形成起重要作用。选择性地形成一个C–C和两个C–Se键,以提供高收率的40个新的苯并硒吩。
