The temperature-dependent behavior within anionic phospho-Fries rearrangements (apFr) of P(O)(OFc)n(EAr)3-n (Fc = Fe(eta5-C5H5)(eta5-C5H4); E = O; Ar = phenyl, naphthyls, (R)-BINOL, [3]ferrocenophanyl; E = N, 1H-pyrrolyl, 1H-indolyl, 9H-carbazolyl; n = 1-3) is reported. While Fc undergoes one, the Ph-based apFr depends on temperature. First, the aryls are lithiated and rearranged, followed by Fc and N-heterocycles. Addition of Me2SO4 thus gave methylated Fc, contrary to non-organometallic aromatics giving mixtures of HO and MeO derivatives. The (R)-BINOL Fc phosphate gave Fc-rearranged phosphonate in 91% de. Exchanging O- with N-aliphatics prevented apFr, due to higher electron density at P. Also 1,2-N?C migrations were observed. X-ray analysis confirms 1D H bridge bonds for OH and NH derivatives. The differences in reactivity between N-aliphatic and N-aromatic phosphoramidates were verified by electrochemistry. The redox potentials revealed lower values for the electron-rich aliphatics, showing no apFr, preventing a nucleophilic attack at P after lithiation. Redox separations for multiple Fc molecules are based on electrostatic interactions.
