以二溴甲基苯(o, m, p)为原料, 分别与2-巯基苯并咪唑环化合成相应的含硫苯并咪唑环蕃, 实验发现二溴甲基取代位置对反应结果有很大影响, o-位取代很易生成[1:1]型环化产物, p-位取代则主要得到链状产物, m-位取代环化产物较复杂, 但以[2:2]型环化产物为主. 产物结构通过1H NMR, IR, HRMS进行了表征, 并得到了1-3a的X射线单晶衍射晶体结构, 对其晶体结构进行了分析.

The novel sulfur-containing benzimidazole cyclophanes were synthesized from bis(bromomethyl)benzene (o, m, p) and 2-benzimidazolinthion, respectively. The reaction showed that bromomethyl positions effected the aim compounds very much. It was easy for o-substituted to generate the [1:1] type cyclization product. p-Substituted obtained chain product, and m-substituted benzene pruduced the [2:2] type cyclization compound as main product. The lead compounds were characterized by 1H NMR, IR, HRMS, and the structure of 1-3a was determined by X-ray diffraction method.

Key words: benzimidazole cyclophane, synthesis, characterization, crystal structure
