This work reports a green method for the synthesis of aryl selenocyanates via a three‐component reaction of arylboronic acids, Se powder, and trimethylsilyl cyanide (TMSCN) under metal‐free and additive‐free conditions. Remarkably, TMSCN acts as not only the substrate, but also the catalyst. Various selenaheterocycles can be also accessed with a catalytic amount of TMSCN.
这项工作报告了一种在无金属和无添加剂条件下通过芳基硼酸,硒粉和三甲基甲硅烷基氰化物(TMSCN)的三组分反应合成芳基硒氰酸酯的绿色方法。显着地,TMCSN不仅充当底物,而且充当催化剂。还可使用催化量的TMSCN来获得各种硒杂环。
