WebDuring the reaction the hydroxyl group of the carboxylic acid is converted to a chlorosulfite intermediate making it a better leaving group. The chloride anion produced during the reaction acts a nucleophile. Example Mechanism 1) Nucleophilic attack on Thionyl Chloride 2) Removal of Cl leaving group 3) Nucleophilic attack on the carbonyl WebGrignard reagents react with CO2 to give carboxylic acids after protonation with aqueous acid. This reaction, called carboxylation, forms a carboxylic acid with one more carbon atom than the Grignard reagent from which it is prepared. [Pg.754]
