Upgrading ethanol to -butanol as biofuels is an important topic for sustainable chemistry. Herein, a CpIr complex bearing a functional 2,2'-carbonylbibenzimidazole ligand [CpIr(2,2'-COBiBzImH)Cl][Cl] was designed and synthesized. In the presence of a catalyst (0.1 mol %) and CsCO (6 mol %), the highest yield of updated -butanol is up to 37% with 80% selectivity. NH units in the ligand are crucially important for the catalytic activity of the iridium complex.
将乙醇升级为生物燃料丁醇是可持续化学的一个重要课题。在此，设计并合成了一种带有功能性2,2'-羰基联苯并咪唑配体的CpIr配合物[CpIr(2,2'-COBiBzImH)Cl][Cl]。在催化剂（0.1 mol%）和CsCO（6 mol%）存在的情况下，升级后的丁醇最高产率可达37%，选择性为80%。配体中的NH单元对铱配合物的催化活性至关重要。
