A number of B-sigma-metallocarboranes have been prepared by oxidative addition of carboranyl boron-hydrogen bonds to an iridium complex. The complexes are models for intermediates in the transition metal catalyzed exchange of deuterium gas for hydrogen at terminal B-H bonds, and do themselves actively catalyze such exchange. Spectra are reported for 3-PPh32Ir HCl-1,2-C2B10H11.
