Free radicals formed during the photolysis of solutions containing di-t-butyl peroxide and fluoro-acetals such as 1,1-diethoxy-2-fluoroethane and substituted 1,3-dioxolanes, have been studied by e.s.r. Spectroscopy. Only the radicals formed initially by hydrogen abstraction were detected, although product analysis by g.c.–m.s. Indicated that certain of the cyclic radicals rearranged to acyclic species
通过esr光谱法研究了在含有二叔丁基过氧化物和氟代缩醛的溶液(例如1,1-二乙氧基-2-氟乙烷和取代的1,3-二氧戊环)溶液中光解过程中形成的自由基。尽管通过gc–ms的产物分析表明某些环状自由基重排为无环物种,但仅检测到最初由氢提取形成的自由基。关于自由基的优选构型,讨论了esr参数。
