  摘要：

  The reaction of [ZnCl2(THF)(2)] with 1,2-{NH(PMeS2)}(2)C6H4 (Mes = 2,4,6-Me3C6H2) yielded the unusual Zn-II complex [ZnCl2(1,2-{N(PHMes(2))}(2)C6H4-kappa(2)N,N')] (1), in which a proton transfer from nitrogen to phosphorus had occurred. ZnR2 reacted with 1,2-{NH(PMes(2))}(2)C6H4 to give the zwitterionic compounds [ZnR{1-N(PMes(2))-2-N(PHMes(2))C6H4-kappa(2)N,N'}] (R = Pr (2a), Et (2b)). The bis-amido complex [Zn{1-N(PMes(2))-2-N(mu-PMes(2))C6H4-kappa(3)N,N',P}](2) (3) was obtained from ZnCl2 and 1,2-{LiN(PMes(2))}(2)C6H4. The Zn-II alkoxide complex [Zn{1-N{PMes(2)CH(2)CH(Me)O}-2-N(PMes(2))C6H4-kappa(3)N,N',O}](2) (4) was obtained from the reaction of 2a with propylene oxide. Complexes 1-4 were characterized spectroscopically (H-1, C-13, P-31 NMR; MS; IR) and by X-ray structure determination.

  l The reaction of Li-2[1,2-N(PMes(2))}(2)C6H4], formed in situ from n-BuLi and the corresponding amines, with 1 equiv. of [NiBr2(DME)] gives [Ni1-N(PMes(2))-2-N(mu-PMes(2))C6H4-kappa N-3,N',P-kappa P-1'}](2) (1). After activation by methylalumoxane (MAO), 1 is a highly active catalyst in the oligomerization and isomerization of alpha-olefins such as ethene, propene, isobutene, 1-hexene and 1,5-hexadiene. For ethene oligomerization turnover frequencies (TOFs) range from 3000 to 79015 h (1), depending on the reaction conditions. The TOF for propene oligomerization reaches 1190730 h (1). To our knowledge, catalyst 1, activated by MAO, is the most active catalyst for the oligomerization of propene and outperforms the best known complexes for this reaction. In the reactions with 1-hexene, 1,5-hexadiene and isobutene dimerization and isomerization products were observed. (C) 2008 Elsevier B.V. All rights reserved.

  The reaction of EtAlCl2 with 1,2-LiN(PMes(2))}(2)C6H4 (Mes=2,4,6-Me3C6H2) and of butyloctylmagnesium with 1,2-NH(PPh2)}(2)C6H4 gave [AlEt(1,2-N(PMes(2))}(2)C6H4-kappa(2) N,N,)(THF)] (1) and [Mg(1,2-N(PPh2)}(2)C6H4-kappa(2) N,N`)(THF)(2)] (2), respectively. Complexes 1 and 2 were fully characterised by NMR (H-1, C-13, P-31) and IR spectroscopy and mass spectrometry. Complexes 1 and 2 were employed as catalysts in the polymerisation of B-caprolactone, which produced polymers with a narrow molecular weight distribution. For comparison the polymerisations of epsilon-caprolactone and P-butyrolactone were carried out with the Zn complex [ZnPr1-N(PMes(2))-2-N(PHMes(2))C(6)H(4-)kappa (NN)-N-2}] (3) as catalyst, which produced polymers with narrow molecular weight distributions and high molecular weights.
