Abstract
Abstract Addition of Grignard reagents to ethyl-[N-(diethoxyphosphoryl)] formimidate, 3 followed by aqueous workup and treatment of the resultant diethyl phosphoramidates with p- toluenesulfonic acid in ethanol gives, depending upon the organomagnesium reagent used, the corresponding tosylates of primary or secondary amines in moderate to good yields. The diethoxyphosphoryl moiety remains unchanged upon treatment of 3 with Grignard ...
