A palladium catalyzed selective B(3)–H activation/oxidative dehydrogenative coupling for the synthesis of bis(o-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^II and Pd^IV was proposed. This work is the first example and the most efficient protocol for synthesis of bis(o-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(o-carborane)s in related fields.

钯催化选择性B（3）–H活化/氧化脱氢偶联反应合成双（邻-碳硼烷）s

钯催化的选择性B（3）-H活化/氧化脱氢偶联反应，用于合成与B（3）-B（3'）和B（3）-B（6'）键连接的双（邻-碳硼烷）是第一次开发。提出了一种可能的机制，该机制涉及通过Pd ^II和Pd ^IV逐步激活B（3）-H和B（3'/ 6'）-H键。这项工作是合成与B（3）–B（3'）和B（3）–B（6'）键连接的双（邻-碳硼烷）的第一个示例和最有效的协议，这具有重要的参考意义用于双（邻-碳硼烷）的设计，合成及其在相关领域的应用。
