Abstract
On the basis of a study of the basic properties of 2H,6H-2,6-dimethyl-4-amino-1,3,5-dithiazine and its N-acyl derivatives it was concluded that N-acyldithiazines exist primarily in the amino form in methanol and acetone, regardless of the type of substituent (donor or acceptor) in the acyl fragment of these molecules. The intramolecular interrelationships between the exocyclic substituent and the protonation center in the investigated compounds correspond to the criteria of the ortho effect of nitrogen-containing heteroaromatic compounds.
