戊二酸(1)与3-芳基-4-氨基-5-巯基-1,2,4-三唑(2a～2o)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(3a～3o). 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 (3a～3o) were synthesized in good yields by condensation of pentanedioic acid (1) with 3-aryl-4-amino-5-mercapto-1,2,4-triazoles (2a～2o) in the presence of phase transfer catalyst tetrabutylammonium iodide and phosphorus oxychloride. The structures of 3a～3o 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
