The cyclization reaction between N‐substituted dithiocarbamates (1) and N‐substituted N‐chloromethylcarbamoyl chlorides (2) gives 3,5‐disubstituted tetrahydro‐2‐thioxo‐2H‐1,3,5‐thiadiazin‐4‐ones (3). In order to decide among the theoretically possible structures 3‐5, the compounds 6a,b, containing a thioxo group instead of an oxo group as in 3a,b, as well as the S‐oxide derivative of 3a was also established by X‐ray structure determination.
