Abstract

The reaction of potassium salt of 5-(2,4-dichlorophenyl)-1,3,4-oxadiazoline-2-thione with dimethyl sulfate was carried out in water and HMPT. It was shown that the nature of the solvent affects the ratio of the formed products of S- and N-methylation. The alkylation of 5-aryl-1,3,4-oxadiazoline-2-thiones with isomeric butyl chlorides showed that the reaction takes place only with n-butyl chloride with the formation of the corresponding S-butyl-substituted derivative.
