comparatively fast and efficient catalyst for carrying out electrophilic substitution reactions of indoles with various aldehydes/ketones/triethylorthoformate, yielding excellent amount of bis(indolyl)methanes/tris(indolyl)methanes. The merits of this protocol are avoidance of any external energy source, minimal reaction time, simple and easy procedure and high yield under solvent free room temperature condition
氯三甲基硅烷被发现是用于进行吲哚与各种醛/酮/原甲酸三乙酯的亲电子取代反应的相对快速和有效的催化剂,可产生优异量的双(吲哚基)甲烷/三(吲哚基)甲烷。该方案的优点是避免了任何外部能源,最短的反应时间,简单易行的程序以及在无溶剂室温条件下的高收率。该方法的多功能性已经用各种醛/酮进行了测试,并获得了令人满意的结果。
