Abstract

Site selective C–H bond activation/C–C bond formation is an ideal target for organic chemists owing to the ubiquitous nature of C–H bonds in natural products. A particular aryl C–H bond can be predictably activated by a directing group. However, the majority of strong and weak coordinating directing groups have been implemented for ortho­-C–H bond activation/C-alkenylation. More recently, meta-C–H functionalization has been promoted by fine-tuning directing templates. In this short review, we have summarized recent progress in palladium-catalyzed directing group/template-assisted ortho/meta-C–H olefination.
