Oxo and Carbonylation Reactions,Many organic compounds react with carbon monoxide in the presence of a nucleophile and a suitable catalyst to give aldehydes, carboxylic acids, esters, ketones etc. The versatility of this type of reaction has led to many industrial applications. Many of these reactions have special names.
