环氧化合物是一类重要的有机合成中间体,制备方法甚多,大都利用有机过氧酸与烯烃的环氧化反应制得。由于有机过氧酸易分解,使用时不够安全,因而使其应用受到一定限制。过硼酸钠(NaBO_3·4H_2O)是一种工业上大量生产的无机过氧酸盐,常用作洗涤剂的添加剂。它在有机反应中的应用则相对甚少。Rashid等曾在碱性水溶液中用它将某些醌类化合物氧化成相应的环氧化合物。McKillop等最近报道,在醋酸介质中,过硼酸钠可将芳香 Epoxy compounds is an important class of organic synthesis intermediates, preparation methods are many, most of the use of organic peroxy acid and olefin epoxidation obtained. As the organic peroxy acid is easy to decompose, not safe enough to use, so its application is subject to certain restrictions. Sodium perborate (NaBO 3 · 4H 2 O) is an industrially mass-produced inorganic peroxyacid commonly used as an additive to detergents. It is relatively less used in organic reactions. Rashid and others used it in alkaline aqueous solution to oxidize certain quinone compounds to the corresponding epoxy compounds. McKillop et al. Recently reported that sodium perborate can be aromatic in acetic acid media
