Diethyl dicarbonate (diethyl pyrocarbonate, DPC) is an excellent reagent1,2) for the preparation of carbonate derivatives of amines, phenols1), alcohols3) as well as for the preparation of carboxylic acid esters2). It is not necessary to use pyridine or any other acid binding agent in the reaction as in case of chlorocarbonate esters, therefore, the reaction products are obtained directly on evaporating
