Synthesis and Structure of Novel 1-Imino-1λ4,2,4,6-thiatriazines

O,O'-Dimethyldiisobiurete 1 is cyclisized with N-arylsulfonyl sulfinyl amines 4a-c to 1λ4,2,4,6-thiatriazines 9a-c.The reaction with corresponding sulfur diimides 7a-c leads to identical 1λ4,2,4,6-thiatriazines 9a-c.Methylation products from 9c with diazomethane are isolated by column chromatography.The cyclization mechanism with a substituted imido sulfurous diamide intermediate is discussed.
