Phase Transfer Catalyzed Synthesis of 1, 2-Bis[(3-aryl)-s-triazolo-[3, 4-b]-[1, 3, 4]thiadiazole-6-yl]ethanes
摘要:
A series of new 1, 2-bis[(3-aryl)-s-triazolo[3, 4-b]-[1, 3, 4]thiadiazole-6-yl]ethanes were synthesized in 50-82% yield by cyclization of 3-aryl-4-amino-5-mercapto-1, 2, 4-triazole with butanedioic acid in the presence of POC13 and tetrabutylammonium iodide as phase transfer catalyst.
