A carboxylic acid molecule (R COOH) is subjected to an electric field in a micro-reactor (11). The molecule decarboxylates to form a radical (R<.>). Two radicals (R<.>) can dimerise to form the product (R-R). It is believed that the reaction occurs away from the electrodes used to apply the electric field (but may also occur at the electrode surfaces).
