A facile approach for synthesis of diaryl- and dialkyl- substituted monophosphino o-carboranes by rhodium(I)-catalyzed phosphine-directed B(3,6)-H activation is developed for the first time. Upon switching rhodium(I) to palladium(II), the C-arylated and B(6)-halogenated products were obtained using tBuOLi and Li2CO3 as base, respectively. These discoveries provide some simple and efficient routes that could enable modification of monophosphino o-carboranes.

单膦基邻甲硼烷的过渡金属催化区域选择性功能化。

首次开发了一种通过铑（I）催化的膦定向的B（3,6）-H活化来合成二芳基和二烷基取代的单膦基邻碳氢化合物的简便方法。将铑（I）转换为钯（II）后，分别使用tBuOLi和Li2CO3作为碱，获得了C-芳基化和B（6）卤代的产物。这些发现提供了一些简单有效的途径，可以使单膦基邻-碳氢化合物改性。
