Application

This 2-pyridone ligand developed in the laboratory of Jin-Quan Yu binds to palladium and accelerates non-directed C-H functionalization. Developed for C-H olefination and carboxylation with arene as the limiting reagent, the Wang-Yu ligand enables diversification of drugs, synthetic intermediates, and other bioactive small molecules.

The directed activation of carbon-hydrogen bonds (C-H) is important in the development of synthetically useful reactions, owing to the proximity-induced reactivity and selectivity that is enabled by coordinating functional groups. Palladium-catalysed non-directed C-H activation could potentially enable further useful reactions

Catalytic oxidative C-H bond functionalization reactions that proceed without requiring stoichiometric amounts of external oxidants or pre-functionalized oxidizing reagents could maximize the atom- and step-economy in chemical syntheses. However, such a transformation remains elusive. Here, we report that a photo-driven

Meta-C-H functionalization of benzylamines has been developed using a PdII /transient mediator strategy. Using 2-pyridone ligands and 2-carbomethoxynorbornene (NBE-CO2 Me) as the mediator, arylation, amination, and chlorination of benzylamines are realized. This protocol features a broad substrate scope and is

The Yu program centers around the discovery of catalytic carbon–carbon and carbon–heteroatom bond forming reactions based on C–H activation. Target transformations are selected to enable 1) the use of simple and abundant starting materials such as aliphatic acids, amines and alcohols, and 2) disconnections that drastically shorten the synthesis of a drug molecule or a major class of biologically active compounds.
