Article abstract of DOI:10.1246/bcsj.59.179

Trichloroacetaldehyde tosylhydrazone acts as an excellent precursor of diazodithioacetate which is generated by treatment of the hydrazone with sulfide ion.This spontaneously cyclizes it to 5-mercapto-1,2,3-thiadiazole.The precursor also gives a 5-amino-1
