用电子自旋共振技术对自旋捕捉剂α-苯基-N-叔丁基氮氧化物(PBN)的两种常用合成方法进行了比较分析,并对方法进行了改进,提出了用 H_2O_2代替 C_6H_5COOOH 对缩合物 PhCH=NBu~1进行氧化反应,得出一种操作简单,产率高,而且引进杂质少的新合成方法。
Two common methods of synthesis of α-phenyl-N-tert-butyl-oxynitride (PBN) as spin trapping agent were comparatively analyzed by electron spin resonance technique and the method was improved. H 2 O 2 C_6H_5COOOH oxidation of the condensate PhCH = NBu ~ 1, resulting in a simple operation, high yield, and the introduction of new impurities less synthesis.
