The first example of palladium-catalyzed ortho-C–H arylation of aryl and benzyl Weinreb amides was developed, in which HOTf was used as a key promoter.

Cleavage Step

<em> </em><p>We report the development of Pd(II)-catalyzed C(sp<sup>3</sup>)–H arylation of Weinreb amides. A pyridinesulfonic acid ligand is designed to accommodate the weak, neutral coordinating property of Weinreb amides via preserving the cationic character of Pd center through zwitterionic assembly of Pd/ligand complexes. DFT studies of the C–H cleavage step indicate that the superior reactivity of 3-pyridinesulfonic acid ligand compared to pyridine, Ac-Gly-OH, and ligandless conditions originates from the stabilization of overall substrate-bound Pd species.</p><em> </em>
