white crystals or powder
Uses
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.
Uses
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.
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.
