The Chlorination of Some 4-Chloro-2,6-dimethylphenols. Some Addition Reactions of Substituted 4,6-Dichloro-2,6-dimethylcyclohexa-2,4-dienones

Abstract

Reactions of 4,6-dichlorocyclohexa-2,4dienone (4c) with chlorine in acetic acid and with chlorine in acetic acid containing sodium acetate are described, as are the corresponding reactions for a mixture of the 4,5,6-trichloro-(4b) and 3,4,6-trichloro-cyclohexa-2,4-dienone (5b). X-Ray crystal structures are reported for compounds (3b), (7), (9b), (11) and (13).
