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 in tandem, sharing two oxygen atoms. These compounds can be viewed as double esters 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, a chemical reagent.
