戊二酸(1)与3-芳基-4-氨基-5-巯基-1,2,4-三唑(2a2o)在相转移催化剂四丁基碘化铵和POCl3作用下, 高收率合成了一系列新的1,2-双[3-芳基-1,2,4-三唑并[3,4-b]-1,3,4-噻二唑-6-基]丙烷(3a3o). 其结构经IR, 1H NMR, MS和元素分析确证.

A series of 1,3-bis[3-aryl-1,2,4-triazolo[3,4-b]-1,3,4-thiadiazole-6-yl]propanes (3a3o) were synthesized in good yields by condensation of pentanedioic acid (1) with 3-aryl-4-amino-5-mercapto-1,2,4-triazoles (2a2o) in the presence of phase transfer catalyst tetrabutylammonium iodide and phosphorus oxychloride. The structures of 3a3o were confirmed by IR, 1H NMR, MS spectra and elementary analyses.

Key words: bis-1,2,4-triazolo[3,4-b]-1,3,4-thiadiazole, synthesis, phase transfer catalysis
