XXVI. Chlorination of arylisoxazoles

  • Published:
Chemistry of Heterocyclic Compounds Aims and scope

Abstract

3,5-Diarylisoxazoles in acetic acid are smoothly converted to 4-chloro derivatives by the action of chlorine in situ. A side reaction is subsequent addition of hypochlorous acid, which proceeds under the influence of excess chlorine. It is convenient to use tert-butyl hypochlorite for the chlorination of more reactive arylisoxazoles.
