The synthesis of amobarbital, using diethyl malonate and urea as the starting material has to be proposed. Concept introduction: Malonic ester synthesis is used to prepare carboxylic acids of the desired length. The malonic ester is reacted with an alkoxide base which removes a alpha hydrogen. The anion so formed is reacted with an alkyl halide . The anion abstracts the alkyl group from the alkyl halide. On heating, decarboxylation takes place which gives the desired carboxylic acid .

Question

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.
