| Abstract: | A novel and efficient synthesis of 1,3,4-thiadiazines, bis-1,3,4-thiadiazoles, 1,2,4]triazino3,4-b]1,3,4]thiadiazine, and thiazolines is reported from the reaction of α-haloketo hydrazonoyl halides with carbonothioic dihydrazide or its analogues. The structures were elucidated on the basis of their elemental analysis, spectral data and an alternative synthetic route. |
