Chemistry of Heterocyclic Compounds Aims and scope

Abstract

On hydrogenation in neutral ethanolic solution in the presence of a Raney nickel catalyst, 1, 2, 4-trisubstituted 3, 5-dioxopyrazolidines undergo hydrogenolysis at the N-N bond. The enolate anions of these compounds and the fixed enolic form are stable to hydrogenolysis.
