The reaction between {CeCp*2H}2 with CO2 in thf resulted in a new cerium(III) carbonate species, {Ce(Cp*)2(thf)}2(μ-η21-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.

{CECP *之间的反应2 H} 2与CO 2在THF中产生了一个新的铈(III)碳酸酯物种,{铈(CP *)2(THF)} 2(μ-η 2:η 1 -CO 3) 。对这种机理的研究表明,桥联的氧配合物{CeCp * 2(thf)x } 2(μ-O)是中间的,它可以由开环和从含氧溶剂(如thf或通过插入CO 2并从所得的亚甲基二醇酯中间体中消除甲醛。
