Synthesis and Photochemistry of Phenyl Subtituted-1,2,4-Thiadiazoles; 15N-Labeling Studies

, 2005
Photochemistry studies of phenyl substituted-1,2,4-thiadiazoles have revealed that 5-phenyl-1,2,4-thiadiazoles 31, 90, 98, 54 and 47 undergo a variety of photochemical reactions including photofragmentation, phototransposition, and photo-ring expansion ...

Synthesis and biological screening of some halogenated thiadiazoles and triazoles

, 2010
89-95 Acid hydrazide 1 is treated with aryl isothiocyanates to get corresponding thiosemicarbazides 2. Compounds 2 in acidic medium give thiadiazoles 3 and in basic medium give triazoles 4. These compounds are synthesized by conventional method and ultra

Anticonvulsant activity of some substituted 1,3,4-thiadiazoles

, 2001
Some 5-[4-(benzoylamino)phenyl]-2 substituted amino-1,3,4-thiadiazoles have been synthesized previously in our laboratory. The structures of these compounds were elucidated using UV, IR and Mass spectroscopic methods besides elemental analyses.
