Abstract: | Summary Together with a partial cracking of the butyl group, 2-n-butylpyridine under the conditions of contact with alumina-chromia catalyst at 500–600 underwent dehydrocyclization at the nitrogen atom with the formation of indolizine, and at the carbon atom with the formation of quinoline. Indolizine and quinoline were also identified in the transformation products of 3-n-butylpyridine.Translated from Izvestiya Akademii Nauk SSSR, Khimicheskaya, No. 12, pp. 2216–2218, December, 1965 |
