  Synthesis and reactivity of bis-4-pyrone and bis-4-pyridinone dichlorotin(IV) compounds

  摘要：

  A number of tin(IV) complexes, Sn(LL)2X2, have been prepared in which LL is a 4-pyronate or 4-pyridinonate ligand and X is chloride or alkoxide. UV-vis, IR and NMR (H-1, C-13, Sn-119) spectra are reported for these complexes. Reactivities have been established through kinetic studies of nucleophilic substitution in acetonitrile solution. Ligand effects on spectra and reactivity are discussed and compared with those for similar metal(IV) complexes, especially of titanium.

  Six co-ordinate tin(IV) complexes of the type SnL2X2 have been prepared (where HL is a monobasic chelating ligand and X = Cl, Br or I). They have been characterised by elemental analysis, 1H and 119Sn NMR, positive-ion fast atom bombardment and electron-impact mass and vibrational spectroscopy. Three distinct 119Sn NMR chemical shift ranges are observed depending on the halogen, demonstrating the relationship

  已经制备了六种SnL 2 X 2的配位锡（IV）配合物（其中HL是一元螯合配体，X = Cl，Br或I）。它们的特征在于元素分析，1 H和119 Sn NMR，正离子快原子轰击，电子碰撞质量和振动光谱法。取决于卤素，观察到三个不同的119 Sn NMR化学位移范围，表明了锡核的屏蔽与卤素的电负性之间的关系。几何异构现象通常在NMR时间尺度上较慢，并且在某些情况下，通过可变温度获得慢速和快速交换光谱119Sn NMR光谱。报告了两个实施例的晶体结构。两者都具有与卤化物顺式的非晶体C 2对称性。该结构代表不同的构型异构体，进一步说明了溶液中异构体之间的容易的相互转化。
