n of alkenes with anilines has been developed for the atom-economical synthesis of 2-substituted propanamides bearing an α-stereocenter. A novel phosphoramidite ligand L16 was discovered which exhibited very high reactivity and selectivity in the reaction. This asymmetric Markovnikov hydroaminocarbonylation employs readily available starting materials and tolerates a wide range of functional groups
This work reports a simple and efficient method for the copper-catalyzed redox-neutral transformation of alkyl nitriles using eco-friendly diaryliodonium salts and leading to N-arylacetamides. The method features high efficiency, broad substrate scope and good functional group tolerance.

Highly efficient and regioselective synthesis of amides from simple starting materials remains a great challenge. Herein, we reported a highly efficient hydroaminocarbonylation of alkenes and alkynes with amines and CO gas catalyzed by a soluble heterogeneous Pdcatalyst (Pd@PPOC), in which ultrafine Pd nanoparticles (NPs) were homogeneously dispersed in a well-defined and discrete triphenyl phosphine-built-in
The highly enantioselective synthesis of chiral amides was achieved by an asymmetric Wolff rearrangement. A bifunctional phosphoric acid catalyst not only expedited the transformation but also controlled the enantioselectivity. The developed method enables the asymmetric addition between potent nucleophilic reagents and ketene species and provides a new approach to chiral amides.
