Abstract
Quinolines and 1,2,3,4-tetrahydroquinolines were obtained by heating quaternary salts of pyridylethylated ketones with sulfites of primary amines in an ampul. 1-Tetralone or substituted 2-tetralones are formed as side products. Substituted 1,4-dihydroquinolines were also identified among the reaction products by Chromatographic mass spectrometry.
