A beta-arylation of primary sp(3)C-H bonds on simple amides such as pivalamides with aryl iodides/ CF3CO2Ag has been established successfully at 120 degrees C in a Pd(OAc)(2) (catalyst)/CF3CH2OH (solvent) system. Pivalamides including (BuCONH2)-Bu-t, (BuCONHR)-Bu-t, and (BuCONR2)-Bu-t undergo the arylations smoothly to afford beta-aryl pivalamides in moderate to good yields. Various aryl iodides are available bearing either electron-donating or electron-withdrawing substituted groups in the coupling reactions.
