Abstract
Process for the preparation and synthesis of 1-2 aryl-alkyl 3-5 dioxo 4-alkyl pyrazolidines consisting essentially of condensing the malonic derivatives obtained by decarboxylation by reaction between an ester of oxalic acid with the esters of the corresponding aliphatic or aromatic acids , with the aryl or symmetrical alkyl hydrazines, giving rise to the substituted 1-2-aryl-alkyl 3-5 dioxo-4n-pyrazolidines.
