Nice and easy: A very simple synthesis for dibenzopentalenes, which starts from 1‐bromo‐2‐ethynylbenzenes, has been developed. It uses Ni0 complexes (see scheme), from which a relatively stable NiII complex as an important intermediate has been isolated. Dibenzopentalenes with various functional groups can be prepared by the procedure, and their electronic properties are consistent with theoretical
简便易用:已经开发了一种非常简单的二苯并戊烯的合成方法,该方法从1溴2乙炔基苯开始。它使用Ni 0络合物(请参阅方案),从中已分离出相对稳定的Ni II络合物作为重要的中间体。可以通过该程序制备具有各种官能团的二苯并戊烯,其电子性质与理论计算相符。
