An efficient protocol for silver-catalyzed direct radical phosphonation of β-aryl-α,β-unsaturated carbonyl compounds with H-phosphites to afford trans-substituted alkenylphosphonates under microwave irradiation is described. Some notable features of this method are high efficiency, good yield, broad functional groups tolerance, commercially available and cheap catalyst.
