Synthesis of 3,5-disubstituted-5,6-dihydro-4h-1,2,5-oxadiazine-6-thiones 1 and 3,5-disubstituted-1,2,4-thiadiazoles

3,5-Disubstituted-5,6-dihydro-4H-1,2,5-oxadiazine-6-thiones are prepared by the reaction of acetophenone oximes with thiophosgene. The thermal rearrangement of 3-phenyl-5-(p-tolyl)-5,6-dihydro-4H-1,2,5-oxadiazine-6-thione yields the corresponding 1,2,5-th

Synthesis of some novel 1,3,4- and 1,2,4-thiadiazole derivatives

Synthesis and spectral characterization of novel 1,3,4-thiadiazole derivatives including one organo-mercury compound are described. Their structure elucidation was performed by means of spectroscopic and physical methods (IR, 1H NMR, 13/s

1,3-Dipolar Cycloaddition Reactions of Nitrilium Betaines with Aryl Thiocyanates and Selenocyanates

The carbon-nitrogen triple bond of aryl thiocyanates acts as a dipolarophile in 1,3-dipolar cycloadditions.Reaction with nitrile oxides, nitrile sulphides, and benzonitrile N-phenylimide yields, respectively, 5-arylthio-1,2,4-oxadiazoles, -thidiazoles and -triazoles.Aryl selenocyanates behave similarly forming 5-arylseleno-1,2,4-oxadiazoles and -thiadiazoles from nitrile oxides and sulphides.Divergent pathways are followed by the reactions of secondary amines such as piperidine with 5-arylthio-1,2,4-oxadiazoles and -thidiazoles, the former yielding 5-piperidyl-1,2,4-oxadiazoles and the latter dihydro-1,2,4-thiadiazole-5-thiones.
