Abstrakt: Chlorine and bromine addition to 4-aroyloxyimino- and 4-arylsulfonyloxymino-3-methyl-2,5-cyclohexadienones initially occurs at the C5ÍC6double bond. The second chlorine molecule adds at both C2ÍCand C5ÍC6double bonds. The chlorination of 2,5-dialkyl-substituted 4-aroyloxyimino- and 4-arylsulfonyloxymino-2,5-cyclohexadienones involves either of the CÍC bonds in the quinoid ring.
