Palladium‐catalyzed directing group assisted C−H bond activation has emerged as a powerful tool in synthetic organic chemistry. However, only recently, among various directing groups, widely available carboxylate moiety is recognized as a versatile candidate for the regioselective transformations. Notably, palladium‐catalyzed carboxylate directed C(sp 3 )−H bond activation and diverse functionalization is highly challenging and has gained huge attention for its versatile applications. Mono‐ and bidentate ligands have proven to be useful for accelerating the C(sp 3 )−H bond activation step, which helps to control reactivity and selectivity (including enantioselectivity). In this Minireview, we discuss the recent progress made in palladium‐catalyzed C(sp 3 )−H bond functionalization reactions for the construction of C−C and C−Heteroatom bonds with the direction of free carboxylic acid.
