Electron-deficient borole compounds exhibit a pronounced Lewis acidity that is enhanced due to their antiaromatic character so that even weak donors datively coordinate to form Lewis acid–base adducts. This contribution presents the synthesis and structural characterization of Lewis acid–base adducts formed by the reaction of 1-mesityl-2,3,4,5-tetraphenylborole and 4-picoline as well as 1-chloro-2
缺电子硼化合物表现出明显的路易斯酸度,由于其抗芳香性而增强,因此即使是弱供体也会配位配位形成路易斯酸碱加合物。该贡献介绍了由 1-mesityl-2,3,4,5-四苯基硼和 4-甲基吡啶以及 1-氯-2,3,4,5 反应形成的路易斯酸碱加合物的合成和结构表征-具有各种供体的四苯基硼。新化合物通过多核 NMR 光谱和单晶 X 射线衍射技术进行表征,并与相关系统进行比较。
