合成了以邻苯二甲酰亚胺为电子受体,末端三甲基硅烷基醚链为电子给体的新的分子内给受电子体系N-(末端三甲基硅烷基硫杂醚链)邻苯二甲酰亚胺(1)和N-(末端三甲基硅烷基氮杂醚链)邻苯二甲酰亚胺(2).化合物1和2在甲醇中进行光反应,在光诱导下发生分子内单电子转移反应,以很高的产率和很高的区域选择性生成硫杂冠醚(3)和氮杂冠醚(4).化合物1~4的化学结构经核磁共振、质谱的验证.
A new intramolecular electron donor system N- (terminal trimethylsilyl thioether chain) with phthalimide as electron acceptor and terminal trimethylsilyl ether chain as electron donor was synthesized. Phthalimide (1) and N- (terminal trimethylsilanylazetidine chain) phthalimide (2) Compound 1 and 2 were subjected to photoreaction in methanol under light-induced (3) and aza crown ethers (4) were synthesized with high yields and high regioselectivity. The chemical structures of compounds 1 ~ 4 were confirmed by 1H NMR, Mass spectrometry validation.
