(1-Amino-1H-benzimidazol-2-yl)methanol 1 with thionyl chloride at reflux afforded 3-chlorobenzimidazo[1,2-c][1,2,3]thiadiazole 4, which reacted with various nucleophiles to give different products depending on the nature of the solvent. The structures of 4 and di(benzimidazo[1,2-c][1,2,3]thiadiazol-3-yl)sulfide 8 were confirmed by single-crystal X-ray analysis.
(1-氨基-1 H-苯并咪唑-2-基)甲醇1与亚硫酰氯在回流下得到3-氯苯并咪唑[1,2- c ] [1,2,3]噻二唑4,其与各种亲核试剂反应生成不同的产品取决于溶剂的性质。的结构4和二(苯并咪唑并[1,2- c ^ ] [1,2,3]噻二唑-3-基)硫醚8通过单晶X-射线分析证实。
