Abstract
A catalytic system utilizing a polar medium for the Pd-catalyzed amination reaction is described. This system utilizes Pd [P (t-Bu) 3] 2 and a weak base and displays a modest rate enhancement compared to similar existing protocols. Significant functional group tolerance is observed in both amine and aryl halide, including carboxylates, carbamates, nitriles, amides, and esters. Product isolation after filtration and automated reverse-phase ...
