An efficient and novel method using palladium catalyst for the synthesis of benzo[d][1,2]diazepines by [5 + 2] annulation of N-arylhydrazones with alkynes has been developed. This methodology undergoes through eight membered palladacycle serving as a back

When arylhydrazones of α-methyleneketones are treated with thionyl chloride they form 2-aryl-1,2,3-thiadiazolium chlorides in high yield, via the intermediate 1,2,3-thiadiazol-3-ine 1-oxides. The effect of substituents on the course of the cyclization was investigated.
