摘要：
Process for preparing a para-quinone or ortho-quinone derivative, possibly alkoxylated or aryloxylated, which consists in oxidizing respectively the corresponding hydroquinone or pyrocatechic derivative, by means of the complex prepared, in situ or separately, by combining a cuprous salt, a hydrocarbon substituted by a cyano group and molecular oxygen, the oxidation being possibly carried out in the presence of an alkoxylating or aryloxylating agent of the hydroxylated derivative type.
