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

A simple and efficient palladium-catalyzed amidationâhydrolysis reaction has been developed to afford N-aryl monosubstituted carboxamides in good to excellent yields from easily accessible ketone-derived gem-dihaloolefins and aryl amines.

Here we develop a porous monophoshine polymer supported Pd catalyst (Pd/POL-m-3vPPh3) for hydroaminocarbonylation of aromatic alkenes with amines, showing excellent catalytic activity (up to 97% yield) and Markovnikov selectivity (up to 99%).
