Abstract

The reaction between {CeCp∗₂H}₂ with CO₂ in thf resulted in a new cerium(III) carbonate species, {Ce(Cp∗)₂(thf)}₂(μ- η²:η¹-CO₃). Investigations into the mechanism suggest the intermediacy of a bridging oxo-complex, {CeCp∗₂(thf)_x}₂(μ-O), which could either be formed from the ring opening and oxygen abstraction from an oxygenated solvent such as thf or via insertion of CO₂ and elimination of formaldehyde from the resulting methylenediolate intermediate.
