Abstract

Aryl bromides are coupled with N-compounds to give the corresponding arylamines in the presence of a palladium catalyst, a suitable ligand, and a weak base. The catalysts perform well for a large number of different starting material combinations at 100–150° C with drops of toluene or without solvent, and with low catalyst levels (0.12 mol% Pd). The low catalyst amount makes the process environment friendly.
