Studies on Oxidation of Cyclohexene by Molecular Oxygen/Acetaldehyde/Transition Metal Salts System

采用分子氧 /乙醛 /过渡金属盐催化剂体系氧化环己烯合成环氧环己烷 ,此方法与传统的有机过氧化物氧化的方法相比 ,具有安全、简便、高效的特点。通过对影响此反应的过渡金属盐催化剂种类、用量以及反应物配比等主要因素的考察 ,可使氧化反应产物 1,2 -环氧环己烷的收率最高可达 78 2 %。

The exploxidation of cyclohexene was achieved by the catalysis of transition metal salts with molecular oxygen in presence of aldehyde under mild conditions. The method is safer and very convenient in high yield, compared with the traditional oxidizing reagents. Some effects of several factors on the reaction were investigated such as the type of catalyst, the ratio of reactants etc. The yield of cycloexeneoxide reached 78 2%.
