摘要：In accordance with the experimental results hitherto obtained in our laboratories that a ring-substituent group in the 3-position of 1-alkylpyridinium salt directs the oxidation to occur at 6-position to give solely the corresponding 3-substituted 6-pyridone, 1-methyl-and 1-phenethyl-3-phenylpyridinium salts furnished the corresponding 3-phenyl-6-pyridones as the only oxidation product by means of alkaline potassium ferricyanide in fair yields.
