reactivity at ambient pressure. The benzylic CH bonds of xanthene, acridanes, isochromane and related heterocycles could be functionalized with nucleophiles including ketones, 1,3‐dicarbonyl compounds and aldehydes. Electron‐rich arenes could be utilized as nucleophiles at elevated temperatures. The reactions are believed to proceed via autoxidation of the benzylic CH bonds to the hydroperoxides and subsequent
描述了苄基CH键与各种C-亲核试剂的好氧有机催化氧化CC键形成反应。通过在室温下在磺酸催化剂的存在下在升高的氧分压下简单地搅拌底物来进行偶联反应。压力的升高使得广泛范围的亲核底物能够反应,否则在环境压力下显示出较差的反应性。苄Ç 呫吨,acridanes,isochromane及相关杂环的H键可以与亲核试剂包括酮,1,3-二羰基化合物和醛官能化。富电子芳烃可在高温下用作亲核试剂。该反应被认为是通过以下方式进行的苄基CH键的自氧化与氢过氧化物和随后被磺酸催化的亲核取代。
