We report herein a practical approach for regio‐selective B—H/C—H bond activation at azo‐substituted carboranes. The reaction proceeded through Iridium(III)‐induced selective B—H/C—H bond activations based on an azo directing group. Through this strategy, a series of mononuclear, trinuclear and tetranuclear cyclometalated iridium complexes containing Cp*Ir—B or Cp*Ir—C bonds were successfully isolated in a high yield. In this work, efficient routes are developed through one‐pot reactions to prepare polynuclear organometallic complexes.

半夹心铱（III）配合物在偶氮取代的碳硼烷上的区域选择性B-H / C-H键活化

我们在此报告了一种在偶氮取代的碳硼烷上进行区域选择性B / H / C-H键活化的实用方法。该反应通过铱（III）诱导的基于偶氮引导基团的选择性B / H / C-H键活化而进行。通过这种策略，成功地高收率成功地分离了一系列含有Cp * Ir-B或Cp * Ir-C键的单核，三核和四核环金属化铱配合物。在这项工作中，通过一锅法反应开发了制备多核有机金属配合物的有效途径。
