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.

Treatment of quinoline 1-oxide (1) with ethyl chloroformate or tosyl chloride and triethylamine in some lower alcohols affords the corresponding 2-alkoxyquinolines (2a-f) in generally satisfactory yields.Reactions of 2-methylpyridine and 2-methylquinoline 1-oxides lead to the corresponding 2-ethoxycarbonyloxymethyl (3 and 5) and 2-ethoxymethyl derivatives (4 and 6).
