Intermolecular CH acyloxylations of phenols with removable directing groups were accomplished with a versatile rutheniumcatalyst. Specifically, a cationicruthenium(II) complex, formed in situ, enabled the chemoselective CH oxygenations of a broad range of substrates. The catalyst proved tolerant of synthetically valuable functional groups, and the substrate scope included both (hetero)aromatic
