Abstract

The reaction of 1, 4-benzenediols with 1.1 equiv of benzyltrimethylammonium tribromide in dichloromethane in the presence of aqueous sodium acetate at room temperature gave 2, 5- cyclohexadiene-1, 4-diones in good yields. On the other hand, the reaction of 1, 4- benzenediols with a large excess of the reagent in aqueous acetic acid at 40–60° C gave polybromo-substituted 2, 5-cyclohexadiene-1, 4-diones in good yields.
