What is Ethyl potassium malonate?

Chemical properties

white crystals or powder

The Uses of Ethyl potassium malonate

Ethyl potassium malonate (potassium ethyl malonate) may be used to generate (trimethylsilyl)ethyl malonate in situ, which can be acylated to prepare a variety of β-ketoesters or alkylidene malonates.

The Uses of Ethyl potassium malonate

Ethyl potassium malonate is used as a competitive inhibitor of the enzyme succinate dehydrogenase. It acts as a precursor to produce (trimethylsilyl)ethyl malonate, which is utilized to prepare beta-ketoesters by acylation. Further, it reacts with aryl nitriles to prepare beta-amino acrylates in the presence of zinc chloride and a catalytic amount of Hünig's base. In addition to this, it serves as an intermediate for the preparation of ethyl tert-butyl malonate.

What are the applications of Application

Ethyl potassium malonate is a competitive inhibitor of the enzyme succinate dehydrogenase

General Description

Ethyl potassium malonate (potassium ethyl malonate) reacts with aryl nitriles in the presence of zinc chloride and a catalytic amount of Hünig′s base to yield β-amino acrylates. Ethyl potassium malonate is formed as an intermediate during the synthesis of ethyl tert-butyl malonate.
