Covalently bound polystyrene–phosphane hybrids were prepared by a method based on radical emulsion polymerization of styrenes in the presence of a tris( p ‐vinylphenyl)phosphane cross‐linker. These hybrids favor mono‐P‐ligation to transition‐metal complexes and are useful for challenging catalysis, such as Pd‐catalyzed CC/CN couplings with unactivated chloroarenes and Ir‐ or Rh‐catalyzed C(sp 3 )H borylations.
