In this density functional theory study, we use static calculations to establish that a 57-atom Co cluster is the smallest model able to reproduce the adsorption behaviour of carboxylic acids, and ab initio metadynamics to obtain the structure and the free energy landscape for its interaction with valeric acid. The resulting carboxylate is almost unreactive because of the high electron density and this is why reduction of carboxylic acids is more difficult and requires more forcing conditions. Tellurophene-2-carboxylic acid reacts with diazomethane to give 2-methoxycarbonyltellurophene <1972JP1199>. Used to esterify complex mixtures of phenols and alcohols for analysis by GCMS.
