Acid-catalyzed oxidation of alkyl- and benzyl-substituted β-diketones by hydrogen peroxide at 79-120 ˚C in a mixture of an alcohol and a strong acid (sulfuric acid, tetrafluoroboric acid, or perchloric acid) gave the corresponding esters through the formation of bridged 1,2,4,5-tetraoxanes. esters - hydrogen peroxide - oxidations - tetraoxanes - ketones
在乙醇和强酸(硫酸,四氟硼酸或高氯酸)的混合物中,过氧化氢在79-120℃下用酸催化的烷基和苄基取代的β-二酮的氧化反应,生成相应的酯。形成桥接的1,2,4,5-四恶烷。 酯-过氧化氢-氧化-四恶烷-酮
