We report the development of a phosphonium salt as a remarkable activating agent that enables the direct conversion of C2–H bonds of a variety of heterocyclicN-oxides into C2–N, C2–O, or C2–S bonds with high efficiency. The phosphonium salt was prepared on a >150 g scale in a single step and is tolerant of multiple functionalities.

activating agent-promoted deoxygenative aryloxylation/amination. The main challenges in constructing C2–O or C2–N bonds from N-oxides lie in overcoming two side reactions: the reaction between the activating agent and the nucleophile, and the associated reaction at the C4-position. Compared to previous reports, this method benefits from an eco-friendly solvent, short reaction time, simple operation, and wide

Employing (2-pyridyl)acetone as a new supporting ligand, the copper-catalyzed coupling reactions of aryl chlorides, aryl bromides, and aryl iodides with various phenols successfully proceeded in good yields under mild conditions. This reaction displays great functional groups compatibility and excellent reactive selectivity.
