摘要

Abstract The transfer hydrogenation reaction of [1, 2, 3] triazolo [1, 5-a] pyridines with Pd/C/Zn or Pd (OH) 2/C/Zn in water, ethanol or water/ethanol mixture has been explored. 4, 5, 6, 7-Tetrahydrotriazolopyridines were obtained in good to medium yields. In addition, under the same conditions 2-substituted pyridines were also formed as a result of intermediate pyridylcarbene formation, by triazole ring opening and loss of nitrogen. ...
