The structure of compound X in the given reactionis to be determined. Concept Introduction: Cyclic esters are called lactones and are often prepared by the intra-molecular cyclization of hydroxy substituted carboxylic acids . Electrophilic addition to the double bond of unsaturated carboxylic acids gives lactone. The phenylselenolactonization, the electrophilic reagent used is benzeneselenylchloride. Anti addition takes place in this cyclization. A selenoxide is produced by the oxidation of the C 6 H 5 Se substituent. It undergoes elimination to produce a double bond in the lactone by the elimination of the beta hydrogen which is away from the lactone oxygen.

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.
