- Reactions of Sulfur Monochloride with some Aromatic Aldehyde Semicarbazones and Thiosemicarbazones: New Syntheses of Substituted 2,4-Dihydro-1,2,4-triazol-3-ones, 2,4-Dihydro-1,2,4-triazole-3-thiones and 2-Amino-1,3,4-oxadiazoles
-
Treatment of various substituted semicarbazones of aromatic aldehydes with sulfur monochloride yields the corresponding substituted 2,4-dihydro-1,2,4-triazol-3-ones.With thiosemicarbazones, the products are derivatives either of the 2-amino-1,3,4-thiadiaz

- The Chemistry of a 1,3,4-Thiadiazin-6-one
-
2-Dimethylamino-5-phenyl-1,3,4-thiadiazin-6-one (2), the first representative of this ring system, undergoes thermal fragmentation to yield benzonitrile, dimethylcyanamide, and 2-dimethylamino-5-phenyl-1,3,4-thiadiazole; its reaction with 1-diethylaminopropyne results in a mixture of adducts, the 1H-pyridazin-4-one (7) and the 5H-pyridazin-4-one (10).
