摘 要:根据拼合原理,将1-氯芳基-(3,4)-二氯苯基引入吡唑环设计成新颖结构的1-氯芳基-(3,4)-二氯苯基-4-(1,2,4)-三唑基吡唑化合物,并研究其合成工艺。寻求制备具有杀菌活性的化合物5-{[(3-甲基-5-氯-1-(3,4)-二氯苯基)]-吡唑基]-(1,2,4)-三唑-[3,4]-1-硫-(3,4)-二氮-5-[(3,5)-二氯-4-甲基)]苯基-6-[(3-氟-4-硝基)苯基]}环己烷。以3-甲基-(3,4)-二氯苯基-5-氯-5-吡唑啉酮和三氯氧磷为起始原料,经过氯甲酰化、氧化、酯化、肼解、取代、环合、缩合、亲核加成反应制得目标化合物5-{[(3-甲基-5-氯-1-(3,4)-二氯苯基)-吡唑基]-(1,2,4)-三唑-[3,4]-1-硫-(3,4)-二氮-5-[(3,5)-二氯-4-(甲基)苯基]-6-[(3-氟-4-硝基)-苯基]}环己烷。在优化的条件下,目标化合物纯度为99.1%。该工艺简单经济,条件温和,合成工艺减少了溶剂的用量和废物排放量。According to the principle of combination,1-aryl chloride-(3,4)-dichlorophenyl was introduced into pyrazole ring to obtain 1-aryl chloride-(3,4)-dichlorophenyl-4-(1,2,4)-triazole pyrazole compounds with novel structures.The synthesis process was studied to look for the compounds with fungicide activities.The target compounds can be obtained through chloroformylation,oxidation,esterification,hydrazinolysis,replace,cyclization,condensation and electeophilic addition reaction.3-methyl-(3,4)-dichloro-1--phenyl)-5-chlorination-5-pyrazolone and phosphorus oxychloride were used as raw materials.Under optimized conditions,the purity of the target compounds can reach up to 99.1%.The process is simple,economic and mild,reducing the amount of solvent and waste discharge.
