Abstract
A series of aminocyclodiphosph(III)azanes (R1R2N)P[NBut]2P(NR1R2) (R1= H, alkyl, or SiMe3; R2= alkyl) have been prepared by the reactions of ClP[NBut]2PCl with primary or secondary amines, or with NMe(SiMe3)2. In some cases geometrical isomers have been separated by fractional crystallisation and thermal methods. Other cyclodiphosph(III)azanes, (Me2N)P[NR]2P(NMe2) (R = Me or Et), have been synthesised by heating diphosphinoamines (Me2N)2P–NR–P(NMe2)2 (R = Me or Et) in vacuo. Selected physical (1H, 13C, 31P n.m.r., i.r., dipole-moment, and mass-spectral) properties of these derivatives are reported and discussed.
