PALLADIUM-CATALYZED AMINATION OF ARYL TRIFLATES

The conversion of aryl triflates to the corresponding aniline derivati ves was accomplished in moderate to good yield using a catalyst consis ting of the combination of palladium acetate (2 mol %) and either BINA P or Tol-BINAP. In contrast to the corresponding palladium-catalyzed a mination of aryl bromides and iodides, electronically neutral aryl tri flates gave higher yields of arylamines than did electron deficient ar yl triflates, presumably due to the increased rate of base-promoted tr iflate cleavage in electron deficient substrates.
