Abstract The microwave-enhanced reactions of 4-amino-5-mercapto-3-substituent-1,2,4-triazoles with benzoyl chloride or arylaldehydes under solvent-free conditions without catalyst were studied. 3-Substituded-6-phenyl-1,2,4-triazolo[3,4-b]-1,3,4-thiadiazoles were easily prepared by the reactions of 4-amino-5-merecapto-3-substituded-1,2,4-triazoles with benzoyl chloride. 4-Arylideneamino-5-mercapto-3-substituted-1
摘要 研究了4-氨基-5-巯基-3-取代基-1,2,4-三唑与苯甲酰氯或芳醛在无溶剂、无催化剂条件下的微波增强反应。3-取代-6-苯基-1,2,4-三唑并[3,4-b]-1,3,4-噻二唑很容易通过4-氨基-5-巯基-3-取代-1的反应制备,2,4-三唑与苯甲酰氯。4-亚芳基氨基-5-巯基-3-取代的-1,2,4-三唑是通过4-氨基-5-巯基-3-取代基-1,2,4-三唑与芳醛缩合得到的。该方法具有反应时间短、过程环境友好、易纯化、收率高等优点。
