six-coordinate structure. An efficient copper porphyrin-catalyzed cross-dehydrogenative coupling (CDC) esterification reaction between C(sp3)–H and carboxylic acids using di-tert-butyl peroxide (DTBP) as an oxidant was established. The kinetic isotope effect (KIE) indicated that C(sp3)–H bond cleavage was the rate-determining step of this CDC reaction.

铜具有六配位结构。建立了以
二叔丁基过氧化物(
DTBP)为氧化剂的C(sp 3)–H与
羧酸之间有效的
铜卟啉催化的交叉脱氢偶联(CDC)酯化反应。动力学同位素效应(KIE)表明,C(sp 3)–H键断裂是该CDC反应的速率决定步骤。
