  2-Chlorovinyl alkyl ketones react with alkylhydrazines to give mixtures of 1-R-3-R'- and 1-R-5-R'-pyrazoles: The 1-R-3-R'-pyrazoles form through the heterocyclization of 2-chlorovinyl ketone alkylhydrazones whereas in the heterocyclization into 1-R-5-R'-pyrazoles N1-alkyl-N2-(2-acylvinyl) hydrazines are involved. The regiospecific heterocyclization of 2-chloro- and 2,2-dichlorovinyl ketones with arylhydrazines and also of 2,2-dichloro(bromo) vinyl trifluoromethyl ketones with C alkylhydrazines into pyrazoles and 5-chloro(bromo)pyrazoles proceeds through a stage of haloenones hydrazones formation. The study of the structure of the obtained 1-alkyl-3(5)-alkylpyrazoles by means of two-dimenaional H-1 and C-13 NMR spectroscopy and GC-MS method made it possible to assign the proton and carbon signals of isomeric pyrazoles and to establish the diagnostic ions for the pair of 1,3- and 1,5-isomers.
