Pd-catalyzed aerobic oxidative coupling of various benzoic acids with silyl enol esters proceeds via a combination of decarboxylation with sp3 β-C–H bond activation to give Heck-type products. Mechanistic studies reveal this coupling involves in situ generation of olefin from aerobic oxidation of silyl enolate, followed by decarboxylative Heck coupling.
钯各种苯甲酸与甲硅烷基烯醇酯的催化催化好氧氧化偶联是通过脱羧与sp 3 β-C–H键活化的结合进行的,从而得到Heck型产物。机理研究表明,这种偶联涉及从烯基甲硅烷基的好氧氧化中原位生成烯烃,然后进行脱羧化Heck偶联。
