通过三(邻甲苯基)氢化锡与1-乙炔基环己醇和1-乙炔基环戊醇发生加成反应,得到两个加成物:(Z)-1-[2-(三-邻甲苯基锡基)乙烯基]环戊醇(1)和(Z)-1-[2-(三-邻甲苯基锡基)乙烯基]环己醇(2).通过元素分析、红外光谱和核磁共振氢谱等手段对其结构进行了表征.用X射线单晶衍射测定了加成物1和2的晶体结构.二者均为具有分子内O→Sn弱配位的扭曲四面体结构.1属于单斜晶系,P21/n空间群,晶胞参数:a=1.0496(2) nm, b=1.7658(4) nm, c=1.3193(3) nm, β=90.60(3)°, V=2.4451(8) nm3, Z=4, R=0.0317, wR=0.0820.2属于三斜晶系,空间群P1,晶胞参数:a=0.85592(17) nm, b=0.93016(19) nm, c=1.6368(3) nm; α=83.76(3)°, β=82.69(3)°, γ=78.05(3)°; V=12600(4) nm3, Z=2, R=0.0377, wR=0.1030.

(Z)-1-[2-(Tri-o-tolylstannyl)vinyl]cyclopentanol (1) and (Z)-1-[2-(tri-o-tolylstannyl)vinyl]-cyclohexanol (2) were synthesized byadditive reaction of the corresponding tri-o-tolyltin hydride to the triple bond of 1-ethynylcyclopentanol and 1-ethynylcyclohexanol, respectively. Allcompounds were characterized by elemental analysis, IR and 1H NMR spectra. The crystal and molecular structures of 1 and 2 have been determined by single crystal X-ray diffraction analysis. The Sn atoms in 1 and 2 adopt a tetrahedral geometry distorted towards trigonal bipyramid duo to a weak intramolecular interaction between Sn and hydroxyl O atoms [the distances of Sn—O are 0.2771(4) nm for 1 and 0.2764(5)nm for 2]. Compound 1 belongs to monoclinicsystem with space group P21/n, a=1.0496(2) nm, b=1.7658(4)nm, c=1.3193(3) nm, β=90.60(3)°, V=2.4451(8) nm3, Z=4, R=0.0317, wR=0.0820. Compound 2 belongs to triclinic system with space group P1, a=0.85592(17) nm, b=0.93016(19) nm, c=1.6368(3) nm, α=83.76(3)°, β=82.69(3)°, γ=78.05(3)°, V=1.2600(4) nm3, Z=2, R=0.0377, wR=0.1030.
