A palladium-catalyzed crossed biaryl coupling/reduction sequence enables the formation of meta-substituted biaryls via solvent-mediated arylpalladium(II) reduction. Isotope labeling studies determined that the decomposition of 1,2-dimethoxyethane (DME) is indeed involved in the reductive process.
钯催化的交叉联芳偶联/还原序列通过溶剂介导的芳基钯(II)还原实现了间位取代联芳基的形成。同位素标记研究表明,1,2-二甲氧基乙烷(DME)的分解确实参与了还原过程。
