Conclusions
-
1.
Methods for the preparation of dimethyl- and diethylamides of chlorothioformic acid of greater purity based on the reaction of tetraalkylthiuram disulfides with sulfuryl chloride are presented.
-
2.
Reaction of the dimethylamide of chlorothioformic acid with potassium thiocyanate proceeds through a fast dimerization of the initially produced dimethylaminothiocarbonylisothiocyanate, followed by 1,3 (N→S) migration of the dimethylaminothiocarbonyl group to give 2-dimethylamino-4-dimethylaminothiocarbonylthio-1,3,5-thiadiazine-6-thione.
