N,O-bis(diphenylphosphinoyl)hydroxylamine base-induced rearrangement to a phosphonamidic-phosphinic mixed anhydride

The hydroxylamine derivative Ph2P(O)NHOP(O)Ph2 rearranges on treatment with Bu(t)OK-Bu(t)OH; the product contains two dissimilar P atoms (δ(p) 24.2 and 7.9, J(pp) 34 Hz) and is rapidly hydrolysed to a phosphonamidate and a phosphinate, consistent with it being the mixed anhydride Ph(PhNH)P(O)OP(O)Ph2.
