  platform for synthetic methods development. The prominent use of acridinium salts as a sustainable option for photoredox catalysts has driven the development of more robust and synthetically useful versions based on this scaffold. However, more complicated syntheses, increased cost, and limited commercial availability have hindered the adoption of these catalysts by the greater synthetic community. By

  光氧化还原催化是一个快速发展的合成方法开发平台。吖啶盐作为光氧化还原催化剂的可持续选择的突出使用推动了基于这种支架的更强大和合成有用的版本的开发。然而，更复杂的合成、增加的成本和有限的商业可用性阻碍了更大的合成社区采用这些催化剂。通过利用黄嘌呤盐直接转化为相应的吖啶盐作为关键转化，我们提出了迄今为止报道的最具合成用途的吖啶盐的高效且可扩展的制备方法。这种不同的策略也使制备一套新型吖啶染料成为可能，

  (Me2N-TP), that allows us to convert an ortho C-H bond to a C-CH3 bond in aromatics and heteroaromatics bearing simple carbonyl groups under mild oxidative conditions. The reaction is powerful enough to methylate all four ortho C-H bonds in benzophenone. The reaction tolerates a variety of functional groups, such as boronic ester, halide, sulfide, heterocycles, and enolizable ketones.

  近年来，芳烃的铁催化 CH 官能化引起了化学家的广泛关注，但由于需要在底物上精心设计导向基团，迄今为止阻碍了苯甲酸和酮等简单芳香羰基化合物的使用，大大减少了其合成公用事业。我们在这里描述了温和反应性甲基铝试剂和用于金属催化的新三齿膦配体 4-(双(2-(二苯基膦基)苯基)膦基)-N,N-二甲基苯胺 (Me2N-TP) 的组合，这使我们能够在温和的氧化条件下将带有简单羰基的芳烃和杂芳烃中的邻位 CH 键转化为 C-CH3 键。该反应足够强大，可以甲基化二苯甲酮中的所有四个邻位 CH 键。该反应耐受多种官能团，如硼酸酯、
