摘要：

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 C-C/C-N couplings with unactivated chloroarenes and Ir- or Rh-catalyzed C(sp3)-H borylations.
