Preparation of pyridines and nicotinonitrile from piperidines

摘要

A piperidine, such as methyl piperidine is converted to the corresponding pyridine by the use of a supported vanadia catalyst. Nicotinonitrile can be produced by conversion of 3-methyl piperidine to 3-methyl pyridine with a supported vanadia catalyst, followed by ammonolysis to nicotinonitrile by the use of a supported vanadia catalyst.
