Boricacidcatalyzes the monoesterification of malonic acid, likely through a chelation mechanism that is not available to the monoester product. Under more forcing conditions, diesters form to some extent, but conditions can be optimized to favour the monoester product (56–80%). With the easily handled solid acid catalyst, these reactions can be run with excess alcohol as solvent or with stoichiometric
