摘　　要：以马来酰胺为电子受体,以带有末端三丁基锡基的醚链为电子给体,构建分子内给受电子体系。在乙腈、甲醇、30%水-乙腈、30%水-甲醇、丙酮等溶剂中进行了光反应。N-(2三-丁基锡甲氧基)乙基马来酰亚胺经过光诱导单电子转移反应历程得到了环化物7-羟基-5吡-咯酮并吗啉。N-[2-(2三-丁基锡甲氧基)乙氧基]乙基马来酰亚胺经过光诱导单电子转移反应历程得到两种不同的环化物。所有新化合物均经过NMR和EI-MS验证。The intramolecular donor-acceptor system was synthesized by using tributylstannylmethoxyether as the electron donor,and maleimide as the electron acceptor.Photoreactions of N-（2-tributylstannylmethoxy） ethylmaleimide and N-[2-（2-tributylstannylmethoxy） ethoxy] ethylmaleimide were explored respectively in acetonitrile,methanol,30% water-acetonitrile,30% water-methanol,and acetone.A cyclic product was formed via the single electron transfer reaction process of N-（2-tributylstannylmethoxy） ethylmaleimide.Two different cyclic products were formed via different pathways of single electron transfer reaction of N-[2-（2-tributylstannylmethoxy） ethoxy] ethylmaleimide.The structures of all compounds were characterized by EI-MS,and NMR spectroscopy.
