Rhodium-Catalyzed Formation of Phosphorus-Boron Bonds: Synthesis of the First High Molecular Weight Poly(phosphinoborane).
An inorganic analogue of polystyrene, poly(phenylphosphinoborane) represents the first high molecular weight, well-characterized polymer with a backbone of alternating phosphorus and boron atoms. It is accessible by metal-catalyzed "dehydrocoupling" of a primary phosphane-borane adduct (see scheme).
