The chloride ion that is liberated then acts as a nucleophile in a cascade reaction that releases CO 2 and CO as an acid chloride forms. Draw the mechanism. Reaction of a carboxylic acid with thionyl chloride is very similar to reaction with oxalyl chloride, described above. Draw the mechanism of the reaction.he uphill carboxyloids are useful materials in terms of being able to make other compounds. For example, a thioester such as acetyl coenzyme A may be able to make a variety of acyl esters. In the laboratory, acid chlorides are very common starting materials to make other carboxyloids.
