Synthesis and structure of bis(phosphaallyl) complexes with two-co-ordinate phosphorus

Abstract

The compound (2,4,6-Bu^t₃C₆H₂)N(H)[graphic omitted](C₆H₂Bu^t₃-2,4,6) was prepared and its crystal structure determined. It is one of the rare examples of non-symmetrically substituted cyclophosphazanes. A series of bis- and mono-phosphaallyl complexes [[graphic omitted](C₆H₂Bu^t₃-2,4,6)}₂](M = Zn or Cd), [[graphic omitted]Bu^t)₂], [[graphic omitted](C₆H₂Bu^t₃-2,4,6)}₂], [[graphic omitted](C₆H₂Bu^t₃-2,4,6)}₂](R′= Bu^t or adamantyl) and [[graphic omitted](C₆H₂Bu^t₃-2,4,6)}Me] have been prepared from cyclic aminophosphazanes and aminoiminophosphanes. The structure of the spirocyclic bis(1,3-diaza-2-phosphaallyl)zinc complex [[graphic omitted]R′)₂](R = R′= C₆H₃Prⁱ₂-2,6) was determined.
