Reaction of dialkylpyridines with styrene and mass-spectrometric behavior of the reaction products

The reaction of 2,4-dimethylpyridine with styrene gives 2-(3-phenyl-propyl)-4-methyl- and 2-methyl-4-(3-phenylpropyl) pyridine, but in the case of 2-methyl-5-ethylpyridine, the reaction gives only 2-(3-phenylpropyl)-5-ethylpyridine. The mass spectra of the compounds obtained have been studied.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 10, pp. 1376–1378, October, 1984.
