Abstract

The synthesis of several fluorobenzofuroxans by oxidation of fluoroanilines and thermal cyclization of fluoroarylazides is presented. The fluorobenzofuroxans prepared in this study presented tautomerism as evidenced by their NMR data. Benzofuroxans in general have biological activity and are synthetic intermediates for the preparation of several compounds with important pharmaceutical applications.
