The Reaction Between N-Methyl-p-toluohydroxamic Acid and Tervalent Phosphorous Compounds: a Thermal PIII -> PV Rearrangement proceeding by a Radical Mechanism

N-Methyl-p-toluohydroxamic acid (6) reacts rapidly with phosphorus compounds XYPCl (X = Ph, Y = OEt and X,Y = OCH2CH2O) at -60 deg C in the presence of pyridine to give the PIII intermediates (7) which have been characterised by 1H, 13C, and 31P n. m. r. spectroscopy.The intermediates decompose at ambient temperatures with homolysis of the N-O bond to give the isomeric N-phosphine oxides (8), accompanied by varying amounts of O-phosphonylhydroxamic acids (9) N-methyl-4-toluamide, (4) and phosphoryl-radical related products.Evidence for a radical-cage process (at least in part) is obtained from 1H and 31P CIDNP studies.
