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

Answer 1

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.
