Reaction of grignard with carboxylic acid

WebAbstract: In this experiment, students gain the understanding of how to prepare a Grignard reagent (magnesium alkyl/aryl halide) using an anhydrous condition. Through performing this experiment, students understand how to obtain and set up a reaction for alcohols and carboxylic acids by nucleophilic addition of a Grignard reagent to a carbonyl compound or … WebGrignard’s reagent can used for the preparation of carboxylic acids by reaction with carbon dioxide. A Grignard reagent on treatment with carbon dioxide in an ethereal solution followed by hydrolysis of the addition product by a dilute mineral acid yields a carboxylic acid. R-Mg-X + O=C=O → RCOOMgX (H2O/H + ) → RCOOH + X-Mg-OH.
