An efficient and simple palladium-catalyzed approach for the synthesis of aryl ketones from low-cost nitriles and arylhydrazines using molecular oxygen (O2) as sole oxidant via C–N bond cleavage is reported. Various aryl ketones were synthesized in moderate to good yields under mild conditions. A possible mechanism involving the PdII/Pd0 catalytic cycle process is depicted, and a cationic palladium
据报道,一种有效且简单的钯催化方法可通过低成本的腈和芳肼,使用分子氧(O 2)作为唯一氧化剂通过C–N键断裂来合成芳基酮。在温和的条件下以中等至良好的产率合成了各种芳基酮。描述了涉及Pd II / Pd 0催化循环过程的可能机理,并通过ESI-MS检测了阳离子钯中间体。
