reactive C-H bonds are present on the O-phenylcarbamate, selective diarylation can be achieved via quadruple C-Hbond functionalization. This work represents a rare example of using O-carbamates as directing groups for catalytic C-Hbondactivation. Additionally, a palladacycle obtained from an O-phenylcarbamate was prepared and fully characterized. This trifluoroacetate-bridged bimetallic Pd complex
