The electron-transfer quenching of excited acceptors by amines and subsequent chemical reactions have been topics of extensive study. Among the various reactions of the photogenerated radical ion pairs, fragmentation via C-C bond cleavage has been shown to be prominent and often a chemically clean path for aminoalcohols, aminoketones, and other systems, recent experiments have shown that the dehydrofragmentation
胺对受激受体的电子转移猝灭和随后的化学反应已成为广泛研究的主题。在光生自由基离子对的各种反应中,通过 CC 键断裂的断裂已被证明是突出的,并且通常是氨基醇、氨基酮和其他系统的化学清洁途径,最近的实验表明,氨基醇的脱氢断裂是强烈的受体 -依赖并符合一种机制,在该机制中,受体阴离子自由基充当碱以促进供体阳离子自由基在与双电子 Grob 碎裂非常相似的反应中裂解。作者在此报告了 1,2-二叔胺光氧化断裂的研究,
