Herein we report a novel approach to the acceleration of palladium-catalyzed C-H activation reactions. We demonstrated that the utilization of electron-deficient triaryl boranes as Lewis acidic cocatalysts of palladium enables the directed cross dehydrogenative coupling of aldehydes and anilides under mild reaction conditions. Study of the kinetic profile of the transformation reveals a unique, unexpectedly long induction period of the transformation.

Palladium-catalyzed dehydrogenative coupling reactions between acetanilides and benzylic alcohols under aqueous conditions are reported. A wide range of benzophenone derivatives could be obtained in good to excellent yields up to 98 %. Mechanism studies showed that a bimetallic palladium cyclopalladated complex might be involved in the catalysis.

A new mild, practical method for the synthesis of aminobenzophenone derivatives through a three step one-pot reaction sequence involving acylation of anilines, palladium catalyzed cross-dehydrogenative coupling of the formed anilides and the hydrolytic cleavage is reported. The full reaction sequence was performed under aqueous conditions.

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 sp3-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.

Palladium-catalyzed cross-dehydrogenative coupling between anilides and aromatic aldehydes was achieved under aqueous conditions. A wide variety of the desired benzophenone derivatives was isolated in good to excellent yield. The reaction rate acceleration effect of acid and detergent has been demonstrated. Mechanistic insight has been obtained from quantum chemical calculations. Copyright

An efficient and clean method to construct C-C 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 conditions. Copyright
