Syntheses of some novel and symmetrical bis(4-amino-4H-1,2,4-triazole-3-thiols)
摘要:
A series of bis(4-amino-4H-1,2,4-triazole-3-thiols) 3a-e were prepared by condensation reactions of 2,2'-(phenylmethylene) bis(sulfanediyl) diacetic acids 2a-e with thiocarbohydrazide. The starting diacid 2a-e was prepared by reactions of aromatic aldehydes 1a-e with 2-mercaptoacetic acid. The structures of these newly synthesized compounds are characterized by elemental analysis, and infrared and NMR spectroscopy.
