氮-(ω-三丁基锡)烷基邻苯二甲酰亚胺的光诱导单电子转移环化反应

Single Electron Transfor Promoded Photoinduced Cyclization Reactions of N-(ω-Tributylstannyl)alkylphthalimides

氮-(ω-三丁基锡)烷基邻苯二甲酰亚胺在光诱导下生成环化物,溶剂亲核性影响其光反应机制:在强亲核性溶剂中反应按单电子转移(SET)机制进行,并以很高的产率得到环化物;在弱亲核性溶剂中氢转移和单电子转移(SET)机制反应同时存在。

Photoinduced reactons of N-（ω-tributylstannyl）alkylphthalimides produced to ringed compounds.The nucleophily of solvent influenced the mechanism of photoinducedcyclization reactions.The mechanism of photoreaction in solvent with strong nucleophily was SET（single electron transfer） and cyclized products could be obtained in high yield. However for the photoreaction in solvents with weak nucleophily, mechanisms of SET and hydrogen atom abstraction existed together.
