N-hydroxylamines: Influence of Substituents on the Competitive Migration of Aryl and Phenyl Groups in the Lossen-like Rearrangement of their O-Methanesulphonyl Derivatives
The N-hydroxylamines ArPhP(O)NHOH (4) (Ar=p-XC6H4; X=MeO, Me, Cl, NO2) have been prepared from the corresponding phosphinic chlorides (3) using O-(trimethylsilyl)hydroxylamine and converted into the O-methanesulphonyl derivatives

SYNTHESIS OF PHOSPHONIC DICHLORIDES AND CORRELATION OF THEIR P-31 CHEMICAL SHIFTS
Various mono-substituted diethyl arylphosphonates were prepared in good yield by treatment of aryl bromides or iodides with triethyl phosphite in the presence of NiCl2 or alternatively, addition of the aryl grignard reagent to diethyl phosphorochloridate.
