| 摘 要： | 本文用自旋捕捉技术与ESR相结合的方法,研究了九种2-芳基-1,3-二噻烷衍生物与二苯甲酮光化夺氢反应中产生的活泼自由基。结果表明,与硫原子相联的两个碳上的C-H键(即2位和4或6位碳的C-H键),都能发生均裂而生成较稳定的自由基。并均可为ND和TBN捕获而生成两种自由基加合物,其浓度比约为1:1。

| Abstract: | The active radicals produced in the photochemical hydrogen abstraction reactions between benzophenone and 2-ary1-1, 3-dithiolan were studied by combination of spin trapping technique with ESR specroscopy. Results show that the homolytic cleavage of C-H on the 2-C (or 4-C, 6-C) could take place, the pro-duced active radicals CH2 werestabilized by the conjugation of adjacent sulphur atoms and could be trapped by nitrosodurene (ND) (or 2,4,6-tri-t-butylnitrosobenzene(TBN) ) to form two spin adducts the concentration ratio of which was about 1:1. |
