Abstract


Our investigation of electrochemical chlorination and bromination of pyrazoles decorated with electron-withdrawing and electron-donating groups showed that the product yield and composition depended on the substitution at the N-1 atom. We have shown for the first time the significant differences in halogenation reactivity patterns of N‑unsubstituted and N-alkylpyrazoles.
