A Ru II photocatalytic method was developed for the direct mono‐benzoyloxylation of electron‐rich aromatic and heteroaromatic systems even with an excess amount of benzoyl peroxide. The reaction was conducted at room temperature under visible light. The direct Ar C–H benzoyloxylations occur without the assistance of any directing groups and can also tolerate various functional groups that have already shown diverse reactivities in transition‐metal catalysis.
