Abstract
Visible light along with 1 mol % eosin Y catalyzes the direct C-H bond arylation of heteroarenes with aryl diazonium salts by a photoredox process. We have investigated the scope of the reaction for several aryl diazonium salts and heteroarenes. The general and easy procedure provides a transition-metal-free alternative for the formation of aryl-heteroaryl bonds.
摘要
可见光与 1 mol%的曙红 Y 通过光氧化还原过程共同催化芳基重氮盐与杂芳烃的直接 C-H 键芳基化反应。我们已经研究了几种芳基重氮盐和杂芳烃的反应范围。该通用且简便的方法为形成芳基-杂芳基键提供了一种无过渡金属的替代方法。
