A General Route to Alkylene-, Arylene-, or Benzylene-Bridged Ditin Hexachlorides and Hexaalkynides
摘要:
The preparation of alkylene-, arylene-, or benzylene-bridged ditin hexachlorides in high yields from the reaction of the corresponding hexacyclohexylated compounds with tin tetrachloride is described. The tetragonal geometry of the tin atom of 1,4-bis(trichlorostannyl)-butane in the solid state indicates that no intramolecular or intermolecular interaction involving either end of the molecule exists in this compound. The ditin hexachlorides were successfully transformed in the corresponding hexaalkynides, precursors of hybrid materials.

Seven organo-bridged bis[tris(arylchalcogenolato)tin] compounds with the general formulae (R′E)3Sn–R–Sn(ER′)3 (R = –(CH2)4–, 1,4-bis(methyl)benzene, 4,4′-bis(methyl)biphenyl; R′ = Ph, 1-Np, 2-Np; E = S, Se) were synthesized and characterized by means of X-ray diffractometry as well as NMR spectroscopy. Three different conformations of the arylchalcogenolato groups ER′ with respect to the bridging group
具有通式 (R'E)3Sn–R–Sn(ER')3 (R = –(CH2)4–, 1,4-bis(methyl)) 的七种有机桥连双[三(芳基硫属元素)锡]化合物苯,4,4'-双(甲基)联苯;R' = Ph, 1-Np, 2-Np; E = S, Se) 合成并通过 X 射线衍射和核磁共振光谱表征。通过量子化学研究合理化和解释了芳基硫属化合物基团 ER' 相对于桥接基团 R 的三种不同构象。
