During the alkylation of diaza(oxa)cycloalkanethiones with halogenoalkanes in a two-phase system in the presence of potassium carbonate the corresponding N,N'-dialkylthiuronium salts are formed.Heating of the latter under vacuum leads to the elimination of the halogenoalkanes and the formation of N,N'-dialkyldiaza(oxa)cycloalkanethiones, including new crown compounds.The cationic selectivity of the latter with respect to the ions of alkali and alkaline-earth metals was determined.
