photolysis studies of the primaryreaction of benzophenone triplet with aliphatic amines in benzene solution are reported. Quantum yield of formation of benzophenone ketyl radical was 0.9 - 1.0. Quantum yields for reduction of ketone also were determined for various amines, and the effects of tert-butyl alcohol on radical formation was investigated. Data indicated that H is not abstracted from -CH/sub
报告了二苯甲酮三联体与脂肪胺在苯溶液中的主要反应的激光闪光光解研究结果。二苯甲酮羰基自由基形成的量子产率为0.9-1.0。还测定了各种胺的酮还原的量子产率,并研究了叔丁醇对自由基形成的影响。数据表明 H 不是从 -CH/sub 3/ 中提取的,而是从 -NH/sub 2/ 中有效提取的。使用叔胺和仲胺观察到的非常高的量子产率被认为暗示了激基复合物的形成,但伯胺的较低量子产率有条件地归因于较高的电离电位。(BLM)
