Buchwald-Hartwig Cross Coupling Reaction. The Buchwald–Hartwig reaction is a cross-coupling reaction where arylamines or heteroarylamines (pyridineamines) are formed by the reaction of an aryl halide or triflate including heteroaryl (pyridines) halide or triflate with a primary or secondary amine in the presence of a palladium metal catalyst and a base.

The Buchwald–Hartwig amination has been investigated theoretically and experimentally to examine the scope of possible bases under different reaction conditions. Nonpolar solvents resist the formation of new charges. Therefore, the base should be anionic to be able to deprotonate the neutral palladium–amine complex and/or expel the anionic leaving group (bromide).
