The structure of some methyl and benzyl malonate derivatives of pyrimidine
Reaction of 2,4,6‐trichloropyrimidine with sodium dibenzylmalonate in p‐dioxane gave 4,6‐dichloro‐2‐(dibenzylmalonyl)pyrimidine, while reaction of 2,4,6‐trichloropyrimidine with sodium dimethylmalonate yielded both 4,6‐dichloro‐2‐(dimethylmalonyl)pyrimidine and 2,2‐bis‐(4,6‐dichloropyrimidin‐2‐yl)dimethylmalonate. Structural studies using nmr, ir and uv spectroscopy indicate that for the former two compounds in basic solvent, an equilibrium exists between the keto forms and resonance‐stabilized enolate ions.
