✦ Synopsis

Azoles, 31. — Vicarious Nucleophilic Substitution of Hydrogen in Nitrobenzotriazole Derivatives

4‐, 5‐, 6‐ and 7‐Nitrobenzotriazole derivatives 1a‐1f, 4a and 4b react with carbanions of chloromethyl, bromomethyl, and α‐chloropropyl phenyl sulfones (2a‐2c) to give products of the vicarious nucleophilic substitution of hydrogen in ortho and para or exclusively in ortho position with respect to the nitro group. The structures of the products have been determined by means of ^1^H‐NMR spectroscopy. On treating with 2c, 1e gives the unexcepted compound 6.
