- Synthesis of 1λ6- and 1λ4-1,2,6-Thiadiazines from S,S-Dialkylsulfur Diimides
-
1λ6,2,6-Thiadiazines 4a-h, 1λ4,2,6-Thiadiazines 5a-k, 6a,b, and ring-open products 3a-o are synthesized by reaction of dialkylsulfur diimides 1a-g with ethylene derivatives 2a-h. 1λ6,2,6-Thiadiazines 4h,b,c can be converted into 1λ4,2,6-Thiadiazines 5j,6a,b under acid catalysis.The ring-open product 3n leads to 1λ6,2,6-thiadiazine 4a when heated with base.
