A palladium-catalyzed oxidative C–H bond functionalization/ortho-acylation of acetanilides using easily accessible aldehyde as the acyl source is described. In the presence of a Pd(TFA)2 catalyst and tert-butylhydroperoxide at 90 °C in general, an array of ortho-acylacetanilides can be afforded in good yields.

A palladium-catalyzed cascade cross-coupling of acetanilide and toluene for the synthesis of ortho-acylacetanilide is described. Toluene derivatives can act as effective acyl precursors (upon sp(3)-C-H bond oxidation by a Pd/TBHP system) in the oxidative coupling between two C-H bonds. This dehydrogenative Pd-catalyzed ortho-acylation proceeds under mild reaction conditions.

Easy access to o‐acyl acetanilides: A new Pd‐catalyzed ortho‐acylation of acetanilides with both aromatic and aliphatic aldehydes has been developed based on a CH activation process. In the presence of tert‐butyl hydroperoxide (TBHP) as the ideal oxidant, this reaction provides an efficient access to ortho‐acyl acetanilides in good yields (see scheme).
