Description

Ethyl hydrogen malonate is used as a reactant for the preparation of tetramic acids through Dieckmann ring closure and organocatalytic decarboxylative Doebner-Knoevenagel reactions. It is involved in the acylation reactions and Knoevenagel condensation with aldehydes. It is also used in the preparation of gamma-lactones from olefins by intermolecular carbolactonization in presence of Mn(III) acetate as a catalyst.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
