亚硝基清除技术已被用来寻找琥珀酰亚胺基和邻苯二甲酰亚胺基自由基形成的证据。在这项工作中，氮氧化物已被检测到，这是由于形成的第二个抗磁性的清道夫，N-叔丁基亚甲基硝酮。这种硝酮已被独立地合成，并显示出是一个有用的自由基清除剂，并已被用来研究琥珀酰亚胺基或邻苯二甲酰亚胺基自由基的几种前体的反应。认为丁二酰亚胺在甲苯中的光诱导分解是由丁二酰亚胺自由基从甲苯中夺取氢而形成的。
The nitroso-scavenging technique has been used to seek evidence for the formation of succinimidyl and phthalimidyl radicals. During this work nitroxides have been detected which are attributable to the formation of a secondary diamagnetic scavenger, N-t-butyl methylene nitrone. This nitrone has been independently synthesised and shown to be a useful radical scavenger, and has been employed to investigate reactions of several precursors for succinimidyl or phthalimidyl radicals. It is argued that in the photoinduced decomposition of t-butyl succinimide percarboxylate in toluene succinimide is formed by hydrogen abstraction from toluene by succinimidyl radicals.
