Water‐soluble rhodium(I)‐ and ruthenium(II)–tertiary phosphine complexes with meta ‐monosulphonated triphenylphosphine (TPPMS) and 1,3,5‐triaza‐7‐phosphaadamantane (PTA) as ligands catalyze the hydrogenation of aqueous HCO 3 − to HCO 2 − under mild conditions. No amine additive is needed for good turnovers. CO 2 accelerates the reactions with [RhCl(TPPMS) 3 ] catalyst; however, it slightly inhibits the reductions catalyzed by [RuCl 2 (TPPMS) 2 ]. Bicarbonate formed in the reaction of limestone with aqueous CO 2 can also be used as starting material for formate production. Copyright © 2000 John Wiley & Sons, Ltd.
