A facile ortho-acylation of acetanilides by a Pd-catalyzed oxidative C–H activation was developed in which low toxic, stable, and commercially available toluene derivatives were first used as acylation reagents by a tandem reaction to form o-acylacetanilides with moderate to good yields. Inexpensive, safe, and environmentally benign TBHP was proved to be an effective oxidant for these transformations

An efficient and clean method to construct CC bonds has been developed via the acylation reaction of acetanilides with benzylic alcohols using tert-butyl hydroperoxide (TBHP) as oxidant catalyzed by palladium acetate in the presence of triflic acid (TfOH). The acylation reactions exhibit excellent reactivities, and up to 95% yield of the corresponding aryl ketone could be obtained under the optimal

acetates with aldehydes, was presented. Simple bench-top aldehydes were used as the non-toxic acylating agents. This protocol comprises direct coupling with aldehydes without activating the carbonyl group and without the directing group assistance. The strategy was applied to a domino one-potsynthesis of 2-quinolinones via acylation and intramolecularaldolcondensation. Significantly, the strategy was extended
