摘要
Malonic monoester monoanilides, and malonic acid monoanilides and bisanilides are formed by reaction of dialkyl malonates with the respective aniline in the presence of stoichiometric amounts relative to the aniline of an alkali metal alkoxide with the formation of, initially, alkali metal salts of monoester monoanilides or malonic acid bisanilides. By neutralisation, the free malonic monoester monoanilide or malonic acid bisanilide or, by hydrolysis, the malonic acid monoanilides can be prepared from these. Chlorine-substituted anilides of cyclopropyl-1,1-dicarboxylic acid or their monoesters are preferred.
