  • Benzylic oligothioethers as ditopic ligands for Group 6 transition metal carbonyls
    作者:Fiona K. Gormley、Julie Gronbach、Sylvia M. Draper、Anthony P. Davis
    DOI:10.1039/a909313c
    日期:——
    The co-ordination preferences of a family of novel thioethers based on (alkylsulfanylmethyl)benzene were examined. The alkyl chain length and the number and position of the thioether substituents were varied. The ligands were synthesized by coupling the alkanethiol to the appropriate benzyl bromide or via the reaction of benzyl mercaptans with bromoethane; Cs2CO3–DMF was employed as the base–solvent mixture. The molecular structure of hexakis(propylsulfanylmethyl)benzene (L3) and 1,2,4,5-tetrakis(propylsulfanylmethyl)benzene (L4) were obtained at room temperature. Both have a crystallographic centre of symmetry. In L3 the S-propyl substituents (“legs”) alternate “a(bove)” and “b(elow)” the plane of the benzene ring, whereas in L4 the “legs” adopt an abba pattern. Several co-ordination modes of the ligands were observed. Bismetallated tetracarbonyl complexes where the ligand bridges two monometal Group 6 carbonyl fragments (M(CO)4) were generated on reaction of [W(CO)4(MeCN)2] or [Mo(CO)3(MeCN)3] with the ligands L1 and L2. The molecular structures of the resulting complexes [Mo(CO)4}2L] (L = L1 or L2 which are the pentyl analogues of L3 and L4 respectively) show that the conformations of the ligands change radically to accommodate the octahedral geometry about the metal centres. In all cases the metal atoms are chelated by “legs” positioned ortho to each other. Changing the stoichiometry of the reactions does not significantly influence the products.
    考察了基于(烷硫基甲基)苯的一类新型硫醚配体的配位优选。改变烷基链的长度和硫醚取代基的数量和位置。配体通过烷硫醇与合适的苄基溴偶联或通过苯甲硫醇与溴乙烷反应合成;使用了Cs2CO3–DMF作为碱-溶剂混合物。室温下获得了六(丙硫基甲基)苯(L3)和1,2,4,5-四(丙硫基甲基)苯(L4)的分子结构。两者都具有结晶学中心对称性。在L3中,硫丙基取代基(“腿”)交替位于苯环平面“上方”和“下方”,而在L4中,“腿”呈现abba模式。观察到了几种配体的配位模式。通过[W(CO)4(MeCN)2]或[Mo(CO)3(MeCN)3]与配体L1和L2反应,生成了配体桥联两个金属单核6族羰基片段(M(CO)4)的双金属四羰基配合物。得到的配合物[Mo(CO)4}2L](L = L1或L2,分别是L3和L4的戊基类似物)的分子结构显示,为了适应金属中心的八面体几何结构,配体的构象发生了根本变化。在所有情况下,金属原子都被位于彼此邻位的“腿”所螯合。改变反应的化学计量比对产物影响不大。
