Polymer bound lactam enol phosphonates can be easily generated using simple phenol on polystyrene resin. These stable, storable compounds can be released in a diversity cleavage strategy, using Suzuki cross coupling conditions, to provide 2-arylenamides in moderate to good overall yields.

Enol phosphinates and phosphonates can be readily prepared from simple lactams in high yields and are both stable and storable. Both these substrates can be employed successfully in homogeneous Suzuki-Miyaura and Stille cross-couplings protocols. Additionally, the phosphonate group can be immobilised on a phenol-on-polystyrene resin and utilised in a simple diversity linker strategy in which the coupled
