The 2-fold successive electrophilic borylation on one aromatic central core led to a series of C2h-symmetric BN-heteroacenes in excellent yields. For the first time, we introduced trimethylsilyl (TMS) as either leaving group or oriented group for efficiently improving the preparation of BN-embedded polycyclic aromatic hydrocarbons (PAHs). The physical properties of the as-synthesized BN-heteroacenes
在一个芳族中心核上连续2次亲电子化硼化反应,可得到一系列C 2h对称的BN-杂并苯乙酮,收率极高。第一次,我们引入三甲基甲硅烷基(TMS)作为离去基团或定向基团,以有效改善BN嵌入的多环芳烃(PAHs)的制备。可以通过位置异构化或芳族中心核的稠合环数来精确调节固态或溶液状态下合成后的BN-杂蒽的物理性质。
