An oxidative cross-coupling between two alkenes under the dual action of a PdII catalyst and a transient directing group (TDG) is demonstrated. The reaction involves TDG-mediated C(alkenyl)−H activation to generate an endo-palladacycle intermediate, whose formation is promoted by a tailored carboxylic acid additive.
证明了在 Pd II催化剂和瞬态导向基团 (TDG) 的双重作用下两种烯烃之间的氧化交叉偶联。该反应涉及 TDG 介导的 C(烯基)−H 活化,生成内环环中间体,其形成由定制的
羧酸添加剂促进。
