Conformational analysis by means of nuclear magnetic resonance measurement has disclosed that N-[(N-nitrosoalkylamino) methyl] amides newly prepared are in favor of anti form in crystals while in state of solution form syn-anti equilibrium mixture. These nitrosoamines have been found smoothly to generate diazoalkanes by the influence of alkali. In the use of their benzamide analogs a new practically useful means for synthesizing a series of diazoalkanes has been established.
