condensation of anilines with vinyl ethers in the presence of catalytic amount of iodine. Modification of both pyridine and benzene moieties was easily achieved by changing only the vinyl ether and aniline. In this reaction, the iodine species was revealed to show dual behavior; molecular iodine serves as an oxidant, while its reduced form, hydrogen iodide, activates the vinyl ether. The redox reaction between
通过苯胺与乙烯基醚在催化量碘存在下的缩合,成功开发了一种无金属、温和、高效的 2-甲基喹啉合成方法。通过仅改变乙烯基醚和苯胺即可轻松实现吡啶和苯部分的修饰。在该反应中,碘物质表现出双重行为;分子碘充当氧化剂,而其还原形式碘化氢则活化乙烯基醚。这些碘物质之间的氧化还原反应使得能够在该合成方法中使用催化量的碘。
