have lent themselves to the one-step preparation of a number of valuable synthetic motifs that are often difficult to prepare through conventional methods. Herein, we report a β- or γ-C(sp3)–H carbonylation of free carboxylic acids using Mo(CO)6 as a convenient solid CO source and enabled by a bidentate ligand, leading to convenient syntheses of cyclic anhydrides. Among these, the succinic anhydride

An acetyl-protected aminoethyl phenyl thioether has been developed to promote C(sp3)-H activation. Significant ligand enhancement is demonstrated by the realization of the first Pd(II)-catalyzed olefination of C(sp3)-H bonds of freecarboxylicacids without using an auxiliary. Subsequent lactonization of the olefinated product via 1,4 addition provided exclusively monoselectivity in the presence of

PdII‐catalyzed C(sp3)−H olefination of weakly coordinating native amides is reported. Three major drawbacks of previous C(sp3)−H olefination protocols, 1) in situ cyclization of products, 2) incompatibility with α‐H‐containing substrates, and 3) installation of exogenous directing groups, are addressed by harnessing the carbonyl coordination ability of amides to direct C(sp3)−H activation. The method
