In organic chemistry, a tricarbonate is a compound containing the divalent −O−C(=O)−O−C(=O)−O−C(=O)−O− functional group, which consists of three carbonate groups linked in a chain by sharing of oxygen oxygen atoms. These compounds can be viewed as derivatives of a hypothetical tricarbonic acid, HO−C(=O)−O−C(=O)−O−C(=O)−OH. An important example is di-tert-butyl tricarbonate (H3C−)3C−C3O7−C(−CH3)3, an intermediate in the synthesis of di-tert-butyl dicarbonate.[1]
The term tricarbonate is sometimes used for salts that contain three carbonate dianions in their covalent structure or stoichiometric formula, such as cerium tricarbonate Ce2(CO3)3.
