摘要: 本工作采用Young提出的方法,利用二苯基苯并呋喃及硫醚类化合物对单线态氧的竞争反应,通过荧光强度的比较,测定了一系列烷基和芳基硫醚化合物和单线态氧反应的速度常数。对所得结果,联系立体效应和电子诱导效应进行了讨论。

Abstract: Reaction rate constant for the reaction of singlet oxygen with a number of alkyl and aryl sulfides in methanol have been measured by the Young’s method. In this method, the competition reaction observed by the measurement of fluorescence intensity between diphenyl benzofuran and different sulfides with singlet oxygen was used.The results concerning the steric and electronic inductive effect have been discussed.
