γ‐di‐aryl propanones. The salient feature of this strategy involves the sequential hydride transfer, regiospecific condensation, regiospecific dearylation, and aromatization under metal‐free reaction conditions. The synthesis of unsymmetrically substituted triphenylenes by oxidative coupling of the synthesized 1,2,4‐triaryl benzenes has also been demonstrated.
通过简单的碱介导的α-芳基肉桂醇或α,γ-二芳基丙烷的反应,已经开发出一种空前的合成均,杂1,2,4-三芳基苯的方法。该策略的显着特征包括连续的氢化物转移,区域特异性缩合,区域特异性脱芳基化和在无金属反应条件下的芳构化。还证明了通过合成的1,2,4-三芳基苯的氧化偶联合成不对称取代的亚苯撑。
