Tautomerism of N-heterocycles. Part II. 3-Hydroxypyridazin-6-one and 3-mercaptopyridazine-6-thione

Abstract

Ionization constants and u.v. spectra of 3,6-dimercaptopyridazine and its N- and S-methyl derivatives reveal that the parent compound exists in aqueous solution as 3-mercaptopyridazine-6-thione.

3,6-Dihydroxypyridazine, its NN′-dimethyl derivative, and 3-hydroxypyridazine on protonation behave abnormally.
