By the catalytic vapor-phase reaction with cadmium phosphate-acid clay as the catalyst, formation of picoline and aniline from cyclohexanone and ammonia was observed. Similarly, 2, 3-lutidine and o-toluidine were formed from methylcyclohexanone and ammonia, 2, 6-lutidine and m-toluidine from 3-methylcyclohexanone and ammonia, and 2, 4, 6-collidine and 3, 5-xylidine from 3, 5-dimethylcyclohexanone and ammonia. In the reaction of 4-methylcyclohexanone and ammonia, formation of pyridine base was not recognized and only p-toluidine was identified.
2-Picoline and aniline were obtained from the reaction of ammonia and 2-cyclohexenone, considered to be the intermediate of this reaction, and 2, 4, 6-collidine and 3, 5-xylidine from 3, 5-dimethyl-2-cyclohexenone and ammonia.
