✦ Synopsis

Abstruct : Treatment of &,P(O)Cl with MesSiNI-IOSiM~ gives Pr$P(0)NHOSiMes. which is desilylated by methanol giving P&P(O)NHOH. The 0-p-nitrobenz.enesulphonyI derivative of this rearranges with KOBu' in BuYIH, an isopropyl group migrating from P to N and the phosphonamidate R'P(O)(OBu?NIIpi being formed quantitatively. Rearrangement also occurs

N-Phosphinoylhydroxylamines containing only simple alkyl groups (Me, Et, Ps) can be prepared using Me3SiNHOSiMe3; alkyd groups migrate from P to N when the derived O-p-nitrobenzenesulphonates react with base.
