Abstract

The N‑alkylation of some substituted arylazopyrazoles has been studied. The direction of the reaction and the dependence of the yields of alkylation products on the structure of substituents in the initial pyrazoles have been established. The structure of 3,5-dimethyl‑4-(nitrophenyl diazenyl)-1- alkylpyrazoles obtained for the first time was confirmed by NMR 1H-, NMR 13C‑spectroscopy and mass spectrometry
