Transposition of the phosphinoyl groups in the base-induced rearrangements of N,O-bis(diarylphosphinoyl)hydroxylamines

Because the N- and O-phosphinoyl groups can change places prior to rearrangement, Ph2P(O)NHOP(O)Ar2 and Ar2P(O)NHOP(O)Ph2 (Ar = p-tolyl) both give mixtures of two phosphonamidic-phosphimic anhydrides, Ph(PhNH)P(O)OP(O)Ar2 and Ar(ArNH)P(O)OP(O)Ph2, on treatment with KOBu(t) in Bu(t)OH. The transposition of the phosphinoyl groups may involve phosphorane intermediates (7 and 9) having the P atom contained within a three-membered ring.
