complex 1, supported by triflamide-functionalized NHC ligands, catalyzes the hydrosilylative reduction of a range of primaryamides into primaryamines in good to excellent yields under base-free conditions with key functional group tolerance. Catalyst 1 is also effective for the reduction of a variety of tertiary and secondary amides. In contrast to literature reports, the reactivity of 1 towards
An efficient sodium bicarbonate promoted aerobicoxidation reaction to prepare N-monosubstituted α-ketoamides in the presence of n-tetrabutylammonium hydrogensulfate (TBAHS) was described. This reaction provides a very simple and convenient synthetic route to N-monosubstituted α-ketoamides from easily available aryl- or heteroarylacetamides in good to high yields without using toxic reagents and

repurposing n-butyl stannoic acid as a catalyst for direct amidation of carboxylicacids with amines. Notably, efficientamidation observed in comparison with all other catalytic methods reported up until now. The protocol has successfully applied to the synthesis of a variety of amides. Moderate reaction parameters, clean amidation with excellent yields of desired amides, ability to tolerate a variety
attracted much attention of organic chemists. In this paper, we developed a Ni(acac)2-catalyzed activation of unreactive alkanes with formanilides in the presence of carbonmonoxide to furnish moderate to excellent yields of amides. This is the first example of aminocarbonylation of inert alkanes using nickel-based catalyst, and formanilides is disclosed to be an interesting amine source owing to the peculiar
