AbstractThe first confirmed synthesis of methylene malonamide (MeMal) is reported. This monomer was prepared by the thermal elimination or fluoride‐ion‐initiated elimination of trimethylsilyl chloride from α‐chloro‐α(trimethylsilyl‐2‐methyl) malonamide. Spectral data for the monomer are given. MeMal has been shown to be unstable in a variety of protic organic solvents, including water and alcohols, thus giving the appropriate (α‐methyl) substituted malonamides. MeMal is stable in most
