Abstract
The reaction of 4-butyl-1,2-bis(p-chlorosulfonylphenyl)-3,5-dioxopyrazolidine with hydrazine hydrate readily gives the p.p′-disulfonylhydrazine of 1,2-diphenyl-4-butyl-3,5-dioxopyrazolidine, which undergoes hydrazinolysis at the C-N bond. The butylmalonic acid N,N′-bis(p-sulfonylhydrazinophenyl)hydrazide formed is in turn cleaved at the C-N bond under the influence of hydrazine hydrate in aqueous alcohol to form p,p′-bis(sulfonylhydrazino)-hydrazobenzene and butylmalonic acid dihydrazide.
