Аннотация:An efficient procedure for the Pd-catalyzed arylation of diethyl a-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.
