Methods to functionalize inert C–H bonds are a critical focus of synthetic organic chemistry. In this work the authors use computations and experiments to uncover the mechanisms of palladium-catalysed C–H lactonizations in aromatic carboxylic aci

Dehydrogenative transformations of alkyl chains to alkenes through methylene carbon-hydrogen (C–H) activation remain a substantial challenge. We report two classes of pyridine-pyridone ligands that enable divergent dehydrogenation reactions through

Easing oxygen into arenes Although oxygen is all around us, it is often surprisingly difficult to use it for selective chemical oxidations, necessitating more expensive, wasteful alternatives. Li et al. report that careful ligand optimization produce

Pd(II)-catalyzed C-H lactonization of o-methyl benzoic acid substrates has been achieved using molecular oxygen as the oxidant. This finding provides a rare example of C-H oxygenation through Pd(II)/Pd(0) catalysis as well as a method to construct bi

The search for more effective and highly selective C–H bond oxidation of accessible hydrocarbons and biomolecules is a greatly attractive research mission. The elucidating of mechanism and controlling factors will, undoubtedly, help to broaden scop

The functionalization of unactivated carbon–hydrogen (C–H) bonds is a transformative strategy for the rapid construction of molecular complexity given the ubiquitous presence of C–H bonds in organic molecules. It represents a powerful tool for
