Chlorine and bromine addition to 4-aroyloxyimino- and 4-arylsulfonyloxymino-3-methyl-2,5-cyclohexadienones initially occurs at the C5=C6 double bond. The second chlorine molecule adds at both C2=C3 and C5=C6 double bonds. The chlorination of 2,5-dialkyl-substituted 4-aroyloxyimino- and 4-arylsulfonyloxymino-2,5-cyclohexadienones involves either of the C=C bonds in the quinoid ring.
