Abstract
2-Cyano-3,3-bis(methylthio)acrylate and N-arylbenzamidrazones reacted together to give mercapto pyrazole derivatives. The structure of the obtained products was proved by IR, mass, and NMR spectra and elemental analyses. Two-dimensional NMR spectroscopy was used to differentiate between other possible alternative structures. The reaction mechanism is also discussed.
