benzylic C–H acylation reaction furnishing a variety of unsymmetrical ketones. A benzophenone-derived photosensitizer combined with a nickel catalyst has been established as the catalytic system. Both acid chlorides and anhydrides are able to acylate the benzylic position of toluene and other methylbenzenes. The method offers a valuable alternative to late transition metal catalyzed C–H acylation reactions
在本文中,我们报道了直接苄基C–H酰化反应的双重催化体系,提供了多种不对称酮。已经建立了二苯甲酮衍生的光敏剂与镍催化剂的组合作为催化体系。酰氯和酸酐都能够酰化甲苯和其他甲基苯的苄基位置。该方法为后期过渡金属催化的C–H酰化反应提供了有价值的替代方法。
