Synthesis of α-diazo-β-keto esters, phosphonates and sulfones via acylbenzotriazole-mediated acylation of a diazomethyl anion

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

Diazo transfer reaction in solid state

A highly efficient methodology in solid state has been developed for the synthesis of α-diazocarbonyl/sulfonyl compounds from active methylene precursors using tosyl azide or 4-carboxybenzenesulfonyl azide and potassium carbonate, devoid of any aqueous work-up, save a column filtration over silica gel.
