Abstract
The reaction of 2-chloro-1-phenylethane-1,1-dithiol with hydrazine gave an unexpected product, 2-hydrazono-1-phenylethane-2,2-dithiol, which underwent intramolecular ring closure to 5-phenyl-4,5-dihydro-1,2,3-thiadiazole in 69% yield. Elementary steps of the process were studied by quantum-chemical methods, and their kinetic and thermodynamic parameters were determined.
