Malonamide

Description

Malonamide is a dicarboxylic acid diamide that is malonic acid in which both carboxy groups have been replaced by carbamoyl groups. It is functionally related to a malonic acid.

Chemical properties

White crystalline powder

The Uses of Malonamide

Malonamide is used in the synthesis of malonamic acid, malonamate and malonamide derivative of some heterocyclic compounds with antiinflammatory activity.

The Uses of Malonamide

Malonamide is a reagent for fluorimetric determination of reducing carbohydrates. The malonamide-based ionic liquid extractant was used in the extraction of europium(iii) and other trivalent rare earth elements from nitric acid medium.

Definition

ChEBI: Malonamide is a dicarboxylic acid diamide that is malonic acid in which both carboxy groups have been replaced by carbamoyl groups. It is functionally related to a malonic acid.

General Description

The malonamide derivatives are obtained by the one-pot, five-component condensation reaction of isocyanide, Meldrum′s acid, arylidene malononitrile, and two amine molecules in CH₂Cl₂.

Hazard

Mildly toxic by ingestion.

Synthesis

The synthesis of Malonamide is as follows:
A typical reaction was carried out in a 10 mL flask. Benzonitrile (2 mmol), CuII-4 ? (0.2 g), acetaldoxime (6 mmol) and MeOH (4 mL) were stirred at 65 °C for 4 h. The solid was filtered, washed with MeOH and the filtrate evaporated. The residue was subjected to GC-MS analysis and NMR spectroscopy. The filtered catalyst can be recycled after drying at about 150 °C for 1 h.

Purification Methods

Crystallise the amide from water. [Beilstein 2 IV 1887.]
