Abstract
A comparison of the IR and UV spectra of 2-alkyl(aralkyl)amino-4H-1,3-thiazines with the spectra of model compounds showed that the amino form of the aminothiazines predominates. The basicities of the synthesized compounds were determined, and the structure of the cation formed on protonation is discussed.
