## Abstract Rapid __Z__,__E__‐isomerization of nitroenamines RNHCHC(NO~2~)COOCH~3~ in solutions was investigated by dynamic NMR spectroscopy. In weakly basic solvents all the studied nitroenamines isomerize by a thermal mechanism. In pyridine the isomerization proceeds by the thermal mechanism i
