Information about steric hindrance caused by substituents at phosphorus atoms is of great importance in understanding the chemi cal reactivity of organophosphorus compounds and their ability to act as ligands for tran sition metals [1]. Among dicarba-c/oso-dodecaborane(12) derivatives, 1-phenyl-1,2-dicarbac/oso-dodecaborane( 12) has been regarded as too bulky for the preparation of the corres...
