The palladium-catalyzed conversion of aryl and vinyltriflates to aryl and vinyl halides (bromides and chlorides) has been developed using dialkylbiaryl phosphine ligands. A variety of aryl, heteroaryl, and vinyl halides can be prepared via this method in good to excellent yields.

This work delineates the synthesis of N,N-dimethylaniline derivativesfrom dimethylamines and aryl triflates. The palladium-catalyzedC–Nbond formation proceeds in excellent yields, using an unsophisticated catalytic system, a mild base, and triflates as electrophiles, which are readily available from inexpensive phenols. N,N-Dimethylanilines are multifunctional reaction partners and represent useful
