A facile strategy to prepare halogenated cationic BC-centered organoboron analogues of alkenyl halides the reaction between carbodiphosphoranes (CDPs) and aryl dihaloboranes is reported. Structural comparison of the halogen and alkoxy derivatives, as well as detailed computational studies, corroborates the polarized double dative bonding nature of the central BC double bonds.
报道了一种制备卤代烯烃的卤化阳离子型以硼-碳为中心的有机硼类似物的简便策略——碳二亚磷烷（CDP）与芳基二卤硼烷之间的反应。对卤素和烷氧基衍生物进行结构比较以及详细的计算研究，证实了中心硼-碳双键的极化双配位键性质。
