Gold-catalyzed para-selective C–H bond alkylation of benzene derivatives with donor/acceptor-substituted diazo compounds

Abstract

Herein, we report a gold-catalyzed highly site-selective C(sp²)–H functionalization of unactivated arenes with α-aryl-α-diazoesters with electron-withdrawing substituents as induced groups on aryl rings. Furthermore, the induced groups are useful for further synthetic transformations.
