A facile approach to the synthesis of diaryl‐ and dialkyl‐substituted monophosphino‐ o‐ carboranes by rhodium(I)‐catalyzed phosphine‐directed B 3,6 −H activation has been developed for the first time. Upon switching rhodium(I) to palladium(II), C ‐arylated and B 6 ‐halogenated products were obtained by using t BuOLi and Li 2 CO 3 as base, respectively. These discoveries provide some simple and efficient approaches to the modification of monophosphino‐ o‐ carboranes.
