We report a method for the synthesis of α-diazo-β-keto esters, phosphonates and sulfonesvia acylation of corresponding diazomethyl anions with N-acylbenzotriazoles. The N-o-amino-acylbenzotriazoles exhibited an unprecedented transphosphorylation reaction leading to diazoacetyl phenylphosphoramidates.
