Melkonyan, F. S.; Gevorgyan, V.Science of Synthesis: Catalytic Transformations via C—H Activation, (2015164.

2,6-Diaryl-N-phenylbenzamides 172 can be synthesized from N-phenylbenzamides 170 via a double C—H arylation with aryl trifluoromethanesulfonates 171 (Scheme 54).[‌143‌] The reaction is catalyzed by a simple palladium(II) acetate/triphenylphosphine catalytic system and, in general, is more efficient than reaction with aryl halides and leads to the products with higher yield. One example of the employment of an aryl bromide coupling partner is shown in Section 1.1.1.2.2.1.
