SYNTHESIS OF 3,5-DISUBSTITUTED-5,6-DIHYDRO- 4H-1,2,5-OXADIAZINE-6-THIONES1 AND 3,5-DISUBSTITUTED-1,2,4-THIADIAZOLES
摘要:
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-thiadiazine-6-one. The reaction of 3-substituted-1,2,4-thiadiazoles with various reactants gave 3,4-disubstituted-1,2,4-thiadiazoles.
