To draw the product when 1,4-dibromobutane undergoes malonic ester synthesis Concept introduction: Malonic ester synthesis is a process in which an halide is converted to a carboxylic acid with two new carbon atoms (comes from malonic ester). By use of this method two new alkyl groups can be introduced. A general scheme of this synthesis is shown below, Please do remember that if alkyldihalide is used for malonic ester synthesis a cyclic product is expected. (intramolecular malonic ester synthesis) Steps involved in malonic ester synthesis are, Deprotonation of α carbon in malonic acid ester Alkylation of enolate Hydrolysis of ester using aqueous acid Decarboxylation at high temperature

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.
