Pyridazine-3,4,6-trithiol and some N- and S-methyl derivatives

Abstract

Pyridazine-3,4,6-trithiol has been prepared and its pK_a values and U.V. spectra compared with those of some N- and S-methyl derivatives. It is evident that the compound does not exist as the trithiol or as the 1H tautomeric form.
