We have found that (i) the reaction of NADH model compounds with potassium persulphate (PPS) in anionic and non-ionic micelles initiates radical polymerisation of acrylamide and (ii) that reductive desulphonation of 2,4,6-trinitrobenzenesulphonate and 4-carboxy-2,6-dinitrobenzenesulphonate by NADH model compounds in deuterium oxide in the presence of the micelles gives 1,3,5-trinitrobenzene and 3,5-dinitrobenzoic
我们发现(i)NADH模型化合物与过硫酸钾(PPS)在阴离子和非离子胶束中的反应引发丙烯酰胺的自由基聚合,以及(ii)2,4,6-三硝基苯磺酸盐和4-羧基的还原性脱磺酸作用在胶束存在下,NADH模型化合物在氘化氢中的-2,6-二硝基苯磺酸盐分别得到1,3,5-三硝基苯和3,5-二硝基苯甲酸,它们含有3-16%的氘。结果表明,反应通过自由基离子对中间体的多步氢转移而进行,并且胶束能够离解自由基离子对。
