Thermal reactions of 5-bromouracils 1 with a well-known one-electron donor such as N-methylindole (2) or N-methylphenothiazine (13) result in easy reductive debromination, presumably involving an initial electron transfer process which appears to depend largely upon the nature of the substituents at the N(1)- and C(6)-positions of the uracil ring.
5-bromouracils 1 与 N-甲基吲哚(2)或 N-甲基吩噻嗪(13)等众所周知的单电子供体发生热反应后,很容易发生还原脱溴反应,这可能涉及初始电子转移过程,而该过程似乎在很大程度上取决于尿嘧啶环上 N(1)位和 C(6)位取代基的性质。
