Ethoxymethylenemalononitrile Usage And Synthesis
DescriptionEthoxymethylenemalononitrile (EMMN) is an orange solid and the melting point of EMMN is 64–66 °C[1].It is an inexpensive reagent. As a functionalized malono-nitrile, it is widely used to synthesize pyrazoles, pyrimidines and a variety of fused heterocyclic systems.
Chemical PropertiesOff White to Pale Yellow
UsesEthoxymethylene Malononitrile (cas# 123-06-8) is a compound useful in organic synthesis.
UsesChemical intermediate.
PreparationTriethyl orthoformate (67.3 mg, 0.454 mol) and malononitrile (20.0 mg,0.302 mol)  were andded to acetic anhydride (77.2 gm, 0.75 moles) and the mixture was refluxed for 4-5 h at 110-140°C. The reaction was monitored by GC. After the reaction is complete, it is cooled to room temperature. Concentrated the mixture at 70°C at reduced pressure to yield crude solid product and the pure product (Ethoxymethylenemalononitrile) was obtained through purified either by vacuum distillation.
