5-三氟甲基-1，3，4-噻二唑脲的微波合成及生物活性研究

simple and efficient method was developed for the synthesis of 5-(trifluoromethyl)-1,3,4-thiadiazol ureas(2) from heterocyclic amino compounds and 1-phenyl-5-(trifluoromethyl)-1,3, 4-thiadiazol-2-ylcarbamate (1) under solvent conditions using microwave irradiation.The structures of the title compounds 2 were characterized by 1HNMR, LC-MS, elemental analysis and X-ray data. The results of the biological activities of the title compounds indicate that the title compounds have low herbicidal and insecticidal activities, but good fungicidal activities. Some of them have good plant growth regulation activities.
