complete and fairly accurate quantitative picture of the isomerism affecting the nitroenamines R2R3N–C(1)R1C(2)H–NO2(R1= H, Me). The compounds with primary or secondary amino groups (R2 and/or R3= H) exist as solvent-dependent equilibrium mixtures of the intramolecularly hydrogen-bonded Z-form and the E-form; the latter isomer can adopt the Z and/or the Econformation around the C(1)–N single bond when R2≠
