| 中文摘要: |
| 在无溶剂条件下，由羟基苯甲醛,5-取代-3-巯基-4-氨基-1,2,4-三唑,对甲苯磺酸经过室温研磨合成了5-取代-4-羟基苯亚甲氨基-3-巯基-1,2,4-三唑，此化合物再经硼氢化钠还原得到5-取代-4-羟基苯甲氨基-3-巯基-1,2,4-三唑衍生物.其结构分别用IR，NMR 和MS 进行了表征.此方法具有反应条件温和，操作简单，产率高等优点，是一种有效合成5-取代-4-羟基苯甲氨基-3-巯基-1,2,4-三唑衍生物的新方法. |
| 英文摘要: |
| 5-substituted-3-hydrosulfuryl-4-hydroxybenzmethyleneamino-1,2,4-triazole were synthesized by reaction of 5-substituted-3-hydrosulfuryl-4-amino-1,2,4-triazole and hydroxybenzaldehyde in the presence of p-toluenesulfonic acid under solvent-free conditions by grinding at room temperature, and then, the synthesized compounds were reduced to 5-substituted-3-hydrosulfuryl-4-hydroxybenzylamino-1,2,4-triazole , The structures of the products were characterized by IR，NMR and MS. The procedure offers several advantages including milder reaction conditions，easier work-up and higher yields, It is a novel synthesis method of 5-substituted-3-hydrosulfuryl-4-arylmethylamino-1,2,4-triazole. |
