N-硝基-N,N′-二苯基脲衍生物的合成及抑菌活性

采用“一锅法”设计合成了9个N-硝基脲衍生物，收率50.2%-76.8%。通过红外光谱、核磁共振谱及元素分析等测试技术确证了它们的结构。初步杀菌活性测试表明，当浓度为50mg/L时，部分化合物对水稻纹枯菌具有较好的抑菌活性。

Synthesis and Fungicidal Activity of N-nitro-N,N’-diphenyl Urea Derivatives

Nine compounds of N-nitro Urea were obtained by one pot way method. The yield of products was at the range of 50.2%-76.8%. The structures of the compounds were identified by 1HNMR, IR and elementary analysis. Preliminary fungicidal activities tests show that some of these target compounds have good fungicidal activities against Rhizoctonia Solani at the concentration of 50 mg/L.
