애플리케이션
This ligand was developed by the Yu lab to enable the Pd-catalyzed dehydrogenation of aliphatic carboxylic acids through a typically challenging activation of the β-methylene C-H bond. This method is chemoselective to carboxylic acids even in the presence of other enolizable functional groups, and may also viably utilize molecular oxygen as the terminal oxidant for the transformation.

Hydroxylation of aryl carbon-hydrogen bonds with transition metal catalysts has proven challenging when oxygen is used as the oxidant. Here, we report a palladium complex bearing a bidentate pyridine/pyridone ligand that efficiently catalyzes this reaction at ring positions adjacent to

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 palladium-catalyzed β-methylene C–H activation of carboxylic acids, leading to the direct
