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

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

temperature decarboxylative ortho-acylation of acetanilides with α-oxocarboxylic acids has been developed via a novel Eosin Y with Pd dual catalytic system. This dual catalytic reaction shows a broad substrate scope and good functional group tolerance, and an array of ortho-acylacetanilides can be afforded in high yields under mild conditions.

A readily available and highly modular class of chiral P,N,N-ligands based on a structurally flexible nonchiral phosphine-amine framework with an opticallyactive 1,2-diphenylethylenediamine unit bearing a tertiary amine terminus as the chiral source have been developed and successfully applied in the Ir-catalyzed asymmetrichydrogenation of o-amidophenyl ketones. These tridentate P,N,N-ligands exhibited
The C-H activation of aryl amide using readily available Pd(OAc)(2) in the presence of selectfluor is reported. The highly mono-selective introduction of sp(2) hybridized functional groups have been realized. A broad range of aryl-, alkenyl- and keto-aryl amides were prepared using unactivated coupling partners under mild conditions. (C) 2018 Elsevier Ltd. All rights reserved.
