characterisation of a new isoindole-based nitrone spin trap, 1,1,3-trimethylisoindole N-oxide (TMINO). This nitrone and its radical adducts (isoindoline nitroxides) exhibit enhanced stability with respect to other commonly used spin traps and their adducts. We also report EPR trapping studies of this new nitrone with some carbon- and oxygen-centred radicals including alkyl, aryl, hydroxyl and benzoyloxyl
在这里,我们描述了一种新的基于异吲哚的硝酮自旋阱1,1,3-三甲基异吲哚N-氧化物(TMINO)的合成和表征。相对于其他常用的自旋捕集阱及其加合物,该硝酮及其自由基加合物(异吲哚氮氧化物)显示出更高的稳定性。我们还报告了这种新的硝酮与一些以碳和氧为中心的自由基(包括烷基,芳基,羟基和苯甲酰氧基系统)的EPR捕集研究。窄的EPR线宽和所得的氮氧化物自旋加合物的稳定性允许检测反应混合物中预期的自由基以及仲和次要自由基组分。
