Popis:	A number of B-sigma-carboranyl iridium complexes have been prepared by both intra- and intermolecular oxidative addition of terminal boron-hydrogen bonds to iridium(I) species. The products from reactions between 1,2-, 1,7-, or 1,12-C2B10H12 and L2IrCl (L = PPh3 or AsPh3) are trigonal bipyramidal complexes of iridium(III) with axial hydride and chloride ligands, two equatorial L ligands and an equatorial carboranyl ligand sigma-bonded to the metal through one of the boron atoms closest to the carbon atoms. The preparation, characterization and structures of these complexes are discussed, as well as their significance as model intermediates for transition metal catalyzed deuterium exchange at terminal boron-hydrogen bonds.
