Abstract
The reaction of 5-aroylamino-1,3,4-thiadiazote-2(3H)-thiones 2 with hy drazonoyl halides 3 in ethanol in the presence of triethylamine at roo m temperature yields 3,5-disubstituted 1,3,4-thiadiazol-2(3H)-one 4-ar oylthiosemicarbazones 8, via ring-chain tautomerism of the intermediat e spirocycloadducts 7.
