A catalyst-free method for the synthesis of dibenzothiophenes has been developed. The nucleophilic intramolecular cyclization of methylthiolated diazonium salts enables the direct synthesis of dibenzothiophenes under mild reaction conditions. The addition of TEMPO is beneficial for improving the reaction yield by suppressing the formation of by-products, which can be formed via a radical-mediated process
已经开发了一种用于合成二苯并噻吩的无催化剂方法。甲基硫醇化重氮盐的亲核分子内环化能够在温和的反应条件下直接合成二苯并噻吩。添加 TEMPO 有利于通过抑制副产物的形成来提高反应产率,副产物可以通过自由基介导的过程形成。这种简单的方法为合成二苯并噻吩提供了一种替代方法,二苯并噻吩经常存在于有价值的化合物中。
