Palladium catalyzed phosphination and arsination of aryl bromides and triflates using economical and air-stable triaryl phosphines and arsines for the synthesis of aryl phosphines and arsines have been accomplished in the solventless conditions. The rates of the reaction are similiar to those carried out in DMF solvent. The method provides a facile and convenient entry to functionalized aryl phosphines and arsines.
