Radical Copolymerization of a Phosphaalkene with Styrene: New Phosphine‐Containing Macromolecules and Their Use in Polymer‐Supported Catalysis

Abstract

PC bonds mimic CC bonds in the radical-initiated copolymerization of a phosphaalkene 1 and styrene (see scheme). The resulting copolymers 2 have unprecedented phosphine-containing backbones with phosphorus compositions that vary depending on the monomer ratios. These novel functional hybrid inorganic–organic macromolecules are used as polymeric supports for the Pd-catalyzed Suzuki coupling. VAZO=1,1′-azobis(cyclohexanecarbonitrile).
