aryl halides. Three classes of ortho-dual C–H functionalization involving alkylation, amination, and deuterated methylation and five types of ipso-operation including alkenylation, cyanation, methylation, hydrogenation, and alkynylation all proceed well in this procedure. In this conversion, aryl-TTs exhibit satisfactory reactivity and feature the advantage that the leaving TT unit can be recovered.
据报道,使用芳基噻烯鎓(芳基-TT)代替芳基卤化物进行了新型 Catellani 型转化。涉及烷基化、胺化和氘代甲基化的三类邻位双C-H官能化和包括烯基化、氰化、甲基化、氢化和炔基化的五种类型的原位操作在此过程中均进展顺利。在此转化中,芳基-TT表现出令人满意的反应活性,并具有可以回收留下的TT单元的优点。更引人注目的是,这一发现代表了芳基-TT的一种新的化学转化,其中在单一化学操作中实现了连续三官能化。
