Abstract

Procedure for obtaining 6-chloro-3-substituted hydrazino-pyridazines of formula In; **(See formula)** wherein R'1 and R'2 independently signify a hydrogen atom, an alkyl radical with 1 to 6 carbon atoms, or an alkenyl radical with 2 to 5 carbon atoms, with the proviso that when one of the symbols R'1 and R'2 signify a hydrogen atom, the other symbol does not signify a methyl radical, characterized in that 3-hydrazino-6-chloro-pyridazine is reacted with a carbonyl compound of formula II, **(See formula)** wherein R'1 and R'2 have the meanings indicated above, in an organic solvent or, if feasible, with an excess of the compound of formula II.
