Formation of polyphosphorus ligands mediated by zirconium and hafnium complexes

The reactions of R2P-P(SiMe3)Li (R = tBu, iPr, iPr2N) with [Cp2MCl 2] (M = Zr, Hf), [Cp*z.ast;CpZrCl2] and [CpZrCl 3] yielded polyphosphorus (mainly hexaphosphorus) compounds which can be viewed as intermediates between R2P-P(SiMe3)Li and derivatives of 1,2,3,4-tetraphosphabicyclo[1.1.0] butane. Thus R 2P-P(SiMe3)Li can act as a building block for the formation of the P2 ligand and the R2P-P(P2) and R2P-P(P2)P-PR2 moieties. Solid state structures of zirconium(IV) and hafnium(IV) complexes with R2P- P(P2) and R2P-P(P2)P-PR2 ligands were established by X-ray studies.
