摘要: 本文报道了异黄樟素光异构化反应的研究。直接光照或用二苯甲酮为敏化剂时,异黄樟素光异构化反应有利于生成其顺式异构体;以9,10-二氰基蒽(DCA)、9-氰基蒽(CNA)以及四氯苯醌为敏化剂时异构化反应有利于生成其反式异构体。我们利用色谱、色质联用、红外以及质子核磁共振等技术对异黄樟素的顺反异构体进行了分析鉴定,并初步探讨了反应机理。

Abstract: Photoisomerization of isosafrole has been studied. Direct irradiation or triplet sen-sitization results in cis-trans isomerization and the stationary states become richer in cis-isosafrole. When 9,10-dicyanoanthraeene, 9-cyanoanthracene and chloranil are used as sensitizer, electron transfer photoisomerization takes place and the stationary states become richer in the trans-isomer. The reactants and products are identified by GC-MS, IR and NMR. A tentative mechanism for the photoisomerization is proposed.
