Gold-Catalyzed C–O Cross-Coupling Reactions of Aryl Iodides with Silver Carboxylates
Guifang Chen, Bo Xu
Abstract
We have developed a C–O cross-coupling reaction of (hetero)aryl iodides with silver carboxylates via a Au I /Au III catalytic cycle. The transformation featured exclusive chemoselectivity and moisture/air insensitivity. Aromatic and aliphatic (including primary, secondary, and tertiary) silver carboxylates are all suitable substrates. Moreover, this protocol worked well intermolecularly and intramolecularly. Most importantly, good yields were obtained regardless of the substrates’ electronic effect and steric hindrance.
