benzene and methanol. Decar☐ylation and solvolysis ascribable to β- and α-scission respectively are observed in case of seven and eight membered cyclic esters. Larger rings do not undergo these photoreactions thus demonstrating effect of ring size on photoreactivity.
已经在
苯和
甲醇中对7,8,12,14,16和20元环
酯进行了光
化学研究。在七元和八元环状
酯的情况下,观察到分别归因于β-和α-断裂的
十烷基化和溶剂分解。较大的环不经历这些光反应,因此证明了环尺寸对光反应性的影响。
