摘要: 据报道对硝基苯磺酞基乙腈的合成,反应时间长,可采用四水合过硼酸钠(NaBO3·4H2O)作为氧化剂,受到重视.改变文献的反应条件,将不同摩尔比的过硼酸钠在55~65℃分批地加到硫醚的冰醋酸溶液中,可以选择性的得到亚矾和矾,而无氰基的水解反应发生.

关键词: 含氰基硫醚, 选择性氧化, 四水合过硼酸钠

Abstract: When Mckillop's method was used,oxidation of cyano-containing organic sulfidesto the corresponding stilfones with sodium perborate tetrahydrate(NaBO3· 4H2O)causedthe hydrolysis of cyano group.However,with our modified procedure in which the reagentsodium perborate was added in small portions at 55~65℃,sulfones and sulfoxides could beselectively obtained and the cyano group was not touched.

Key words: cyano-containing sulfide, selective oxidation, sodium perborate tetrahydrate
