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 pK
a
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.
本发明涉及一种制备饱和或不饱和内酯的方法。该方法涉及在第一有机溶剂中,在第一酸(pKa小于或等于3)的存在下,将双环化合物或单环化合物与过氧化氢反应,从而形成一个过氧化物。随后,将包含过氧化物的混合物滴加到第二有机溶剂和促进解离的催化剂混合物中,可选地包括第二有机酸。本发明还涉及制备过氧化物的方法。
