The reaction of 1,5-dimethyl-2,4,8-trinitronaphthalene with diethylamine and triethylamine in DMSO and in DMSO–MeOH solvent systems has been studied. 1H N.m.r. investigations have shown that a benzyl type anion is formed due to hydrogen abstraction from the 1-methyl group of the nitroaromatic compound. Kinetic and thermodynamic data for the systems have been determined. The results are explained in
研究了1,5-二甲基-2,4,8-三硝基萘与二乙胺和三乙胺在DMSO和DMSO-MeOH溶剂体系中的反应。1 H Nmr研究表明,由于硝基芳香族化合物的1-甲基夺氢而形成了苄基型阴离子。已经确定了该系统的动力学和热力学数据。根据两种胺和带电产物的溶剂化差异和所用溶剂介质的溶剂化能力差异来解释结果。研究了添加的三乙基氯化铵对1,5-二甲基-2,4,8-三硝基萘与三乙胺在DMSO中反应的影响,动力学变化归因于添加的盐和带电产物之间的离子缔合。
