REACTION OF 3,3-DIMETHYL-2,4-PENTANEDIONE WITH ALKYL- AND ARYLHYDRAZINES

Depending on the conditions and on the substituent, the reaction of 3,3-dimethyl-1,4-pentanedione with alkyl- and arylhydrazines can be used for the synthesis of the corresponding mono- and bishydrazones and also substituted 5-hydroxy-, 5-hydrazino-, or 5-methylene-2-pyrazolines.The addition of trifluoroacetic acid, water, hydrazines, and amines to the latter was studied.For the "unsymmetrical" products from addition of the hydrazines to the substituted 5-methylene-2-pyrazolines an equilibrium or mutual transition between the two 5-hydrazino-2-pyrazoline forms is observed.
