Abstract

Process for obtaining new derivatives of heterocyclic hydrazines and their salts, which comprises the condensation of an acid of the general formula R1-COOH in which R1 represents a thiophen, pyrrolic or N-alkyl-pyrrolic radical which can carry halogen, alkyl, alkoxy or alkylmercapto substituents established in C, with a substituted hydrazine of the general formula H2N-NH-R2 in which R 2 represents an aralkyl radical, an alicyclic hydrocarbon radical with no more than 7 carbon atoms or a straight or branched chain saturated aliphatic hydrocarbon radical, provided with not more than 7 carbon atoms, in the presence of a N, N'-bis-substituted carbodiimide and, if desired, the conversion of the condensation product into a salt.
