报道了一种新的含烯酰胺膦阴离子（dbuP-）的铱（I）配合物的合成及其与CO2的独特反应性。该复合物结合两当量的CO2，并启动高度选择性的反应级联。该反应导致CO2和烯酰胺基配体的可逆裂解。计算分析指出，存在一个相对稳定的Ir-CO2络合物作为反应中间体之前，CO2裂解，这是实验证实。观察到的转化类似于RuBisCO的酶促CO2固定的几个方面。
The synthesis of a new iridium(I) complex containing an enamido phosphine anion (dbuP- ) and its unique reactivity with CO2 is reported. The complex binds two equivalents of CO2 and initiates a highly selective reaction cascade. The reaction leads to the reversible cleavage of CO2 and the enamido ligand as well. Computational analysis points to the existence of a relatively stable Ir-CO2 complex as a reaction intermediate prior to CO2 cleavage, which was confirmed experimentally. The observed transformation resembles several aspects of enzymatic CO2 fixation by RuBisCO.
