A palladium‐catalyzed oxidative acylation of O‐phenyl carbamates with α‐oxocarboxylic acids via selective aromatic CH bond activation is described. This protocol represents the first ortho‐acylation of phenol derivatives, and a catalytic amount of triflic acid additive is crucial for this transformation.
