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.
The photo-reaction of N- (ω-tributyltin polyethoxy ether) phthalimide in methanol solvent was studied and compared with the reported N- (ω-trimethylsilyl polyethoxy ether) Phthalimide in methanol was compared with the photochemical reaction results were found that light-induced single-electron transfer - off tributyltin ring than the light-induced single-electron transfer - off trimethylsilylene ring formation process more efficient High, indicating that increasing the leaving ability of the leaving group can increase the selectivity of the single electron transfer reaction and the yield of the cyclized product.The structures of all new compounds and the final cyclized compounds were confirmed by 1H NMR, 13C NMR and HRMS.
