- Tetrahydro-2-thioxo-2H-1,3,5-thiadiazin-4-ones and their Derivatives Representing a Novel Heterocyclic Ring System
-
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.
