Continuing efforts to establish a more general âuser-friendlyâ protocol for the palladium-catalysed arylation of amines (BuchwaldâHartwig reaction) are described herein. Significant advances have been made through the use of the versatile (SIPr)Pd(methallyl)Cl complex in conjunction with the reliable base lithium hexamethyldisilazide (LHMDS).
