NMR Studies and electrophilic properties of triphenylphosphine-trifluoromethanesulfonic anhydride; a remarkable dehydrating reagent system for the conversion of aldoximes into nitriles

The electrophilic properties of triphenyl(trifluoromethylsulfonyloxy)phosphonium trifluoromethanesulfinate and its corresponding bis(triphenyl)oxodiphosphonium trifluoromethanesulfinate dimer system have been exploited in the development of a mild method for converting aldoximes into nitriles.
