Fungicidal Activities of 1,4-Bis[(3-aryl)-s-triazolo-[3,4-b]- [1,3,4]thiadiazole-6-yl]naphthalenes
摘要:
1,4-Bis[(3-aryl)-s-triazolo[3,4-b]-[1,3,4]thiadiazole-6-yl]naphthalenes 2 were synthesized in high yields by reaction of 3-aryl 4-amino-5-mercapto-1,2,4-triazole I with 1,4-naphthalic acid in the presence Of POCl3 and tetrabutylammonium iodide as catalyst. The structures have been established on the basis of elemental analysis and spectral date. The preliminary antibacterial tests showed that 2b, 2c and 2d exhibited good fungicidal activities against Cerospora beticola sacc.
