Enehydrazines, 34. The Addition of Methylhydrazine to Dimethyl Acetylenedicarboxylate is Reversible

The cyclisation of the enehydrazine 1 to the pyrazolone 5 proceeds by cleavage of 1 to its educts 2 and 3 followed by their recombination to 4.Addition of 2 or 3 supresses the dissociation of 1, furthermore 2 and 3 could be separately captured from 1.
