  Synthesis and Properties of Di-isopropylamino Derivatives of Diphosphanes and Triphosphanes: The X-Ray Structure of ( ⁱ Pr₂N)₂P–P(SiMe₃)₂

  摘要：

  (iPr2N)2PCl (3) reacts with P(SiMe3)2Li yielding crystalline (iPr2N)2P-P(SiMe3)2 (1). Compound 1 crystallizes in the orthorhombic space group Pbca. The lithiation of 1 with BuLi yields (iPr2N)2P-P(SiMe3)Li (2). Compound 2 reacts with 3 with the formation of (iPr2N)2P-P(SiMe3)-P(NiPr2)2 (4) in high yield. Attempts to lithiate 4 with BuLi in THF solution in order to obtain (iPr2N)2P-PLi-P(NiPr2)2 were unsuccessful, probably due to strong electron donation of the iPr2N groups into the P-P-P skeleton in 4.

  The reactions of R2P-P(SiMe3)Li (R = (t)3u, Pr-i, (Pr2N)-Pr-i) with [Cp2MCl2] (M = Zr, Hf), [Cp*CpaCl(2)] and [CpZrCl3] 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 R2P-P(SiMe3)Li can act as a building block for the formation of the P-2 ligand and the R2P-P(P-2) and R2P-P(P-2)P-PR2 moieties. Solid state structures of zirconium(IV) and hafnium(IV) complexes with R2P-P-2(P-2) and R2P-P(P-2)P-PR2 ligands were established by X-ray studies. (C) 2013 Elsevier Ltd. All rights reserved.

  The reactions of diphosphanes R2P-P(SiMe3)(2) (R = Ph, 'Bu, Et2N and 'Pr2N) with [(R-3'P)(2)PtCl2] (R-3'P=Me3P, Et3P, Et2PhP, EtPh2P 3 and p-Tol(3)P) are very complex. The main reaction pathway is splitting of the P-P bond of the parent R2P-P(SiMe3)2 followed by P-31 NMR spectroscopy. The molecular formation of [(R'P-3)(2)Pt}(2)P-2], R2P-PR2 and other products which have been characterized by 3 structures of [(Et2PhP)(2)Pt}(2)P-2], [(p-Tol(3)P)(2)Pt}(2)P-2].2Et(2)O, [mu(2)-(1,2:2-eta-P-2)Pt(PEt3)(2)}(2)Pt(PEt3)(2)Cl}]Cl-+(-) and [(p-Tol(3)P)ClPt(mu-PPh2)(2)Pt(p-Tol(3)P)Cl] have been determined by single-crystal X-ray structural analysis.
