A Pd(II)-catalyzed reaction protocol for the direct carboxylation of benzoic and phenylacetic acid derivatives to form dicarboxylic acids has been developed. The reaction conditions are also applicable for the carboxylation of vinyl C-Hbonds. The first C-H insertion Pd-aryl complex from carboxylic acids has been characterized by X-ray crystallography.
已经开发了用于苯甲酸和苯乙酸衍生物直接羧化以形成二羧酸的 Pd(II) 催化反应方案。反应条件也适用于乙烯基 CH 键的羧化。来自羧酸的第一个 CH 插入 Pd-芳基配合物已通过 X 射线晶体学表征。
