    摘要: The invention relates to a process for preparing saturated or unsaturated lactones. This process involves reacting a bicyclic compound or a monocyclic compound with hydrogen peroxide in the presence of a first acid having a pKa of 3 or less and a first organic solvent, thereby forming a hydroperoxide. The obtained mixture comprising the hydroperoxide is subsequently metered to a mixture of a second organic solvent and a dissociation-enhancing catalyst, optionally comprising a second organic acid. The invention also pertains to a process of preparing the hydroperoxide.
