Palladium(II)-catalyzedhighly regioselective and stereoselective decarboxylative arylation of unactivated olefins with aryl carboxylic acids has been developed. This method is applicable to a variety of unactivated olefins, including allylamides, long chain functionalized olefins and purely aliphatic olefins, leads to the formation of linear E-configured products in high yields. Both electron-rich
(E)-allylamines. It was found that the choice of solvent, olefin substrate and oxidant had an important influence on reaction efficiency, and the use of sterically demanding N,N-diprotected allylamines bearing a carbamate moiety is crucial for securing high regioselectivity and stereoslectivity. This method provides a straightforward approach for the efficient synthesis of various γ-heteroarylated, linear (E)-allylamines
