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
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。

A process for the production of a complex of lactic acid and either ammonia or an amine, comprising reacting one or more saccharides with barium hydroxide to produce a first reaction mixture comprising barium lactate, and contacting at least part of the first reaction mixture with ammonia or an amine and with carbon dioxide, or with the carbonate and/or bicarbonate salt of ammonia or an amine, to produce a second reaction mixture comprising said complex and barium carbonate.
