New synthesis and properties of 3-alkyl-, 3-chloroalkyl-, 3-perfluoroalkyl-, and 3-aryl-1-methyl-(5-halo)pyrazoles from chloro(bromo) vinyl ketones and N,N-dimethylhydrazine

Levkovskaya,Bozhenkov,Larina,Mirskova

, p. 1501 - 1506 (2007/10/03)

A new regioselective heterocyclization was revealed in the reaction of 2-chloro- and 2,2-dichloro-(bromo)vinyl ketones with N,N-dimethylhydrazine to afford 3-substituted 1-methyl(5-halo)pyrazoles. The reaction is accompanied by elimination of methyl halide and formation of up to 90% of N,N,N-trimethylhydrazinium halide as the second product.
