A facile approach to the synthesis of diaryl- and dialkyl-substituted monophosphino-o-carboranes by rhodium(I)-catalyzed phosphine-directed B-3,B-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 tBuOLi and Li2CO3 as base, respectively. These discoveries provide some simple and efficient approaches to the modification of monophosphino-o-carboranes.
