摘要/Abstract
报道了空气条件下温和高效的N-羟基邻苯二甲酰亚胺和铜共同催化N-吡啶吲哚啉的氧化脱氢反应. 已知的N-吡啶吲哚啉的氧化过程只能在过量强氧化剂2,3-二氯-5,6-二氰对苯醌存在下实现, 该反应以空气作为单一的氧化剂, 具有绿色、安全、低成本以及操作简便等优点, 为N-吡啶吲哚啉类化合物氧化生成相应吲哚衍生物提供了一条新的绿色途径.

An efficient and mild N-hydroxyphthalimide and copper co-catalyzed aerobic oxidative dehydrogenation of N-pyridylindolines is developed. The use of air as sole oxidant allows a green, safe, low-cost and simple operation. This method provides an alternative to the known method for the oxidation of N-pyridylindoline derivatives by the use of excess stoichiometric strong oxidant 2,3-dichloro-5,6-dicyanobenzoquinone.
Key words: N-hydroxyphthalimide, dehydrogenation, N-pyridylindolines, air condition, oxidation reaction
