alkyl and ketyl radicals, from aliphatic aldehyde photochemistry were detected by NO spin trapping and EPR techniques. Deuterium effects on EPR spectra and the generation of radicals by 2‐amido‐2‐propyl radical attack on substrate molecules in aqueous solution via hydrogen‐atom abstraction were applied to identify radicals produced photochemically from aldehydes. Aliphatic aldehydes used in the present
脂肪醛光化学中的自由基,如酰基、水合酰基、烷基和羰基自由基,通过 NO 自旋捕获和 EPR 技术检测。应用氘对 EPR 光谱的影响以及 2-酰胺基-2-丙基自由基攻击水溶液中的底物分子通过氢原子提取产生自由基,以鉴定由醛光化学产生的自由基。本研究中使用的脂肪醛是甲醛、乙醛、乙醛-d4、丙醛、异丁醛、异戊醛和叔戊醛。提出了可能的反应机制。版权所有 © 2004 John Wiley & Sons, Ltd.
