A complex generated from Pd[P(o-tol)3]2 and the alkylbisphosphine CyPF-t-Bu is a highly active and selective catalyst for the coupling of ammonia with aryl chlorides, bromides, iodides, and sulfonates. The couplings with this catalyst conducted with a solution of ammonia in dioxane form primary arylamines from various aryl electrophiles in high yields.
