Mono‐ and bimetallic iridium complexes involving novel triscarbene ligands were synthesized and applied to the dehydrogenation of biomass‐derived glycerol. This resulted in affording hydrogen and lactate with the excellent turnover number (TON; 3,240,000) and turnover frequency (TOF; 162,000 h^–¹). The triscarbene ligand in a single frame allowed the formation of bimetallic iridium complexes. This induced the cooperative effect of two iridium ions and rendered excellent TONs and TOFs in the production of hydrogen and lactate.

高效的铱催化甘油制氢和乳酸的生产：双金属铱催化剂快速释放氢

合成了涉及新型三碳烯配体的单金属和双金属铱配合物，并将其用于生物质衍生的甘油的脱氢。这样就提供了氢和乳酸，它们具有极佳的周转率（TON; 3,240,000）和周转频率（TOF; 162,000 h ^–¹）。单框架中的三卡宾配体允许形成双金属铱配合物。这诱导了两个铱离子的协同作用，并在氢气和乳酸的生产中提供了极好的TON和TOF。
