摘要: 本文用光照的1H化学诱导动态核极化技术,研究了安息香及其衍生物的光化反应。并通过不同浓度的自由基捕获剂(PBN)的加入,对所研究体系的CIDNP效应的影响,分析推断了安息香等的光解及其光解自由基的复合的反应机理。并讨论了双取代安息香醚的光反应机理随取代基的变化而有所不同。

Abstract: Photochemical reactions of benzoin and its derivatives have been investigated by photo-CIDNP technique We could deduce that the photochemical reaction products of (a), (c) and (b), (d) were second recombination products by using free radical-trapping agent with different concentrations. We discussed the reason about the variation of reaction mechanisms of (e) and (f) that differed in substituting groups.
