Synthesis of Phenols: Organophotoredox/Nickel Dual Catalytic Hydroxylation of Aryl Halides with Water

A highly effective hydroxylation reaction of aryl halides with water under synergistic organophotoredox and nickel catalysis is reported. The OH group of the resulting phenols originates from water, following deprotonation facilitated by an intramolecular base group on the ligand. Significantly, aryl bromides as well as less reactive aryl chlorides served as effective substrates to afford phenols with a wide range of functional groups. Without the need for a strong inorganic base or an expensive noble-metal catalyst, this process can be applied to the efficient preparation of diverse phenols and enables the hydroxylation of multifunctional pharmaceutically relevant aryl halides.

Expeditious Assembly of Fluorenones through Domino Reactions of Benzoyl Chlorides with Arylboronic Acids Catalyzed by ONO Pincer-like Palladium(II) Complexes

A new set of palladium(II) complexes featuring ONO pincer-type ligands were synthesized and utilized as efficient homogeneous catalysts for the domino reactions of benzoyl chlorides with arylboronic acids to yield a library of fluorenones. The titled reaction proceeded smoothly in H2O/MeOH media at a low catalyst loading (0.1 mol %) under mild reaction conditions in an open flask, and the catalyst could be reused over six consecutive runs. To validate the currently developed methodology for industrial-level applications, a gram-scale synthesis was done. Advantageously, the present protocol does not require any external oxidant, additives, or phase-transfer agents.
