Chlorination of 4-aroyloxyimino-2,5-cyclohexadienones containing alkyl substituents in the quinoid ring yields stable 5,6-dichloro-4-aroyloxyimino-2-cyclohexen-1-ones, whose dehydrochlorination results in 6-chloro-4-aroyloxyimino-2,5-cyclohexadienones. The chlorination and dehydrochlorination processes are highly regioselective: Chlorine adds preferentially across the unsubstituted double bond of the quinoid ring, and dehydrochlorination involves elimination of the chlorine atom from position 5 of the cyclohexene structure.
