Description | Ethoxymethylenemalononitrile (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 Properties | Off White to Pale Yellow | Uses | Ethoxymethylene Malononitrile (cas# 123-06-8) is a compound useful in organic synthesis. | Uses | Chemical intermediate. | Preparation | Triethyl 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.
