                                    An efficient procedure for the Pd-catalyzed arylation of diethyl alpha-diazomethylphosphonate with aryl iodides is described. It can serve as a pathway for the generation of arylated diazophosphonates, which are typically difficult to access. The significance of this methodology was demonstrated via further synthetic transformations of newly synthesized diazo compounds in cyclopropanation, epoxidation, N-H and O-H insertion reactions.
