SYNTHESIS AND STRUCTURE OF BIS(PHOSPHAALLYL) COMPLEXES WITH 2-CO-ORDINATE PHOSPHORUS

The compound H(2))N(H)PN(SiMe(3))P(Cl)N(C(6)H(2)Bu(3)(t)-2,4,6) was pr epared and its crystal structure determined. It is one of the rare exa mples of non-symmetrically substituted cyclophosphazanes. A series of bis- and mono- phosphaallyl complexes [M{(Me(3)Si)NPN(C(6)H(2)Bu(3)(t) -2,4,6)}(2)] (M = Zn or Cd), [Zn(Bu(t)NPNBu(t))(2)], {(4-(PrC6H4)-C-i) NPN(C(6)H(2)Bu(3)(t)-2,4,6)}(2)]. [Zn{R'NPN(C(6)H(2)Bu(3)(t)-2,4,6)}(2 )] (R' = Bu(t) or adamantyl) and 6-Bu(3)(t)C(6)H(2))NPN(C(6)H(2)Bu(3)( t)-2,4,6)}Me] have been prepared from cyclic aminophosphazanes and ami noiminophosphanes. The structure of the spirocyclic bis(1,3-diaza-2-ph osphaallyl)zinc complex [Zn(RNPNR')2(]) (R = R' = C6H3Pr2i-2,6) was de termined.
