摘要
Monohalohydroquinone monocarboxylates are selectively prepared by halogenating a hydroquinone monocarboxylate, or admixture thereof with a hydroquinine dicarboxylate and a minor amount of hydroquinone, with a chlorine, bromine or sulfuryl halide halogenating agent; such monocarboxylates are facilely converted into the corresponding dicarboxylates by acylation. Both the monocarboxylates, e.g., monochlorohydroquinone monoacetate, and dicarboxylates, e.g., monochlorohydroquinone diacetate, are useful organic intermediates.
