of hydroamination and hydroarylation using a gold catalyst to enable and study the reactions between pyrrole-substituted anilines and alkynes. The gold(I)-catalyzed reactions were achieved in toluene at 80 °C over a reaction time of 1−6 h. These reactions are applicable to a variety of aromatic amino compounds and both the terminal and internal alkynes. Substituted pyrrolo[1,2-a]quinoxalines were obtained
在这项研究中,我们开发了一种使用金催化剂进行加氢胺化和加氢芳基化的高效串联方法,以实现并研究吡咯取代的苯胺和炔烃之间的反应。金(I)催化的反应是在80°C的甲苯中于1-6 h的反应时间内完成的。这些反应适用于各种芳族氨基化合物以及末端炔烃和内部炔烃。以中等至优异的产率获得了取代的吡咯并[1,2- a ]喹喔啉。在氘标记研究的基础上,提出了一种推测的机制,该机制涉及通过阳离子金络合物形成分子间CN键和分子内亲核反应。
