Abstract
The action of potassium amide in liquid ammonia on several methyl substituted 3- and 4-bromo(chloro)pyridines, of 5-bromo-2-t-butylpyridine and of 3-bromo (chloro) and 4-bromo(chloro)-2,6-dimethylpyridine has been studied. The results of the reactions indicate the occurrence of derivatives of 3,4-didehydropyridine as intermediates. An interpretation is given of the influence of the substituent and the hetero atom on the course of the aminations.
