研究了N-(ω-三丁基锡聚乙氧基醚)邻苯二甲酰亚胺在甲醇溶剂中的光反应, 并与文献报道的N-(ω-三甲基硅聚乙氧基醚)邻苯二甲酰亚胺在甲醇中的光反应结果进行了比较. 发现光诱导单电子转移-脱三丁基锡成环反应过程比光诱导单电子转移-脱三甲基硅成环反应过程效率更高, 表明提高离去基团的离去能力可以提高单电子转移成环反应的选择性和环化物的产率. 所有新化合物和最终环化物的结构均经1H NMR, 13C NMR, HRMS验证.

关键词: 光诱导单电子转移, 三丁基锡, 三甲基硅, 离去基团, 环化物

The present study investigated the photoreaction of N-(ω-tributylstannylpolyethoxyether)- phthalimides in methanol solution. The results obtained were compared with that reported in previous studies. It is shown that photoinduced single electron transfer cyclization reaction proceeds by destannation at a higher efficiency than the cyclization reaction by desilylation, which suggests a feasibility of increasing the selectivity and productivity of single-electron cyclization reaction through improving the cleavability of the leaving group. The structure of all the new compounds and final cyclic compounds were characterized by using 1H NMR,13C NMR, HRMS technology.

Key words: photoinduced single electron transfer, tributylstannyl, trimethylsilyl, leaving group, cyclocompound
