ABSTRACT:
A process for producing a ring-substituted arene borane which comprises reacting a ring-substituted arene with an HB organic compound in the presence of a catalytically effective amount of an iridium or rhodium complex with three or more substituents, excluding hydrogen, bonded to the iridium or rhodium and a phosphorus organic ligand, which is at least in part bonded to the iridium or rhodium, to form the ring-substituted arene borane. Also provided are catalytic compounds for catalyzing the process comprising an iridium or rhodium complex with three or substituents, excluding hydrogen, bonded to the iridium or rhodium and optionally, a phosphorus organic ligand, which is at least in part bonded to the iridium or rhodium.
