A palladium catalyzed selective B(3)-H activation/oxidative dehydrogenative coupling for the synthesis of bis(-carborane)s connected with B(3)-B(3') and B(3)-B(6') bonds has been developed for the first time. A plausible mechanism involving stepwise activation of B(3)-H and B(3'/6')-H bonds by Pd and Pd was proposed. This work is the first example and the most efficient protocol for synthesis of bis(-carborane)s connected with B(3)-B(3') and B(3)-B(6') bonds, which has important reference for design, synthesis, and application of bis(-carborane)s in related fields.
首次开发了一种钯催化的选择性B(3)-H活化/氧化脱氢偶联反应，用于合成通过B(3)-B(3')和B(3)-B(6')键连接的双( -碳硼烷)。提出了一种合理的机理，涉及钯逐步活化B(3)-H和B(3'/6')-H键。这项工作是合成通过B(3)-B(3')和B(3)-B(6')键连接的双( -碳硼烷)的首个实例和最有效的方法，对双( -碳硼烷)在相关领域的设计、合成及应用具有重要参考价值。
