RhIII carbonate generated from either a peroxocarbonate complex [RhCl(CO4)(PR3)3] or [RhCl3(PR3)3] and Na2CO3, is reduced to RhI by deoxygenation of the carbonate moiety to CO2 by an out-of-sphere phosphane. The reaction takes place in mild conditions and is implied in the catalytic activity shown by RhI in the oxidation of styrene with O2/CO2 mixtures.

Extended labeling experiments have shown that formation of rhodium peroxocarbonate from CO2 and [RhCl(η2-O2(P)3] (P is PEt2Ph or PEtPh2) proceeds through O-O bond cleavage and CO2 insertion. O-transfer to ancillary phosphine ligand to give R3P=O selectively (>85%) involves the Rh-linked O atom of the peroxo group of RhCl(CO4)(P)3.
