Abstract
Cyclohexene is converted to 3,6-diacyloxycyclohexene by reaction with a C.sub.2 to C.sub.6 aliphatic acyclic saturated carboxylic acid and an organic hydroperoxide in the presence of a copper catalyst. The diacyloxycyclohexene is hydrolyzed to the corresponding dihydroxycyclohexene and dehydrogenated to hydroquinone. For example, with acetic acid the cyclohexene is converted to the 3,6-diacetoxycyclohexene which after hydrolysis and dehydrogenation gives hydroquinone.
