In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Pincer Ligand Enhanced Rhodium-Catalyzed Carbonylation of Formaldehyde: Direct Ethylene Glycol Production, published in 2021-01-31, which mentions a compound: 1086138-36-4, mainly applied to rhodium formaldehyde ethylene glycol carbonylation catalyst, Quality Control of Bis(2-(Di(adamantan-1-yl)phosphino)ethyl)amine.
Formaldehyde is one of the most important bulk chems. and is produced on a million tone scale (52 million tons in 2017).[1] Since the middle of the last century, the challenge has remained to produce the valuable ethylene glycol (EG) directly from the C1 building block formaldehyde in a single step. In the systems reported so far, the reaction conditions were very harsh, often with pressures above 400 bar. However, under milder conditions, the selectivity was on the side of glycol aldehyde (GA) and the hydrogenation product methanol. Only traces of EG could be generated in the presence of a Rh catalyst. Herein, the authors describe a new Rh catalyst system with pincer ligand, which allows the direct one pot synthesis of EG from easy to handle paraformaldehyde (PFA) at remarkable mild conditions (70 bar, 100°C) and overcomes the aforementioned limitations with yield up to 40%.
There is still a lot of research devoted to this compound(SMILES：P(CCNCCP(C12CC3CC(C2)CC(C3)C1)C45CC6CC(C5)CC(C6)C4)(C78CC9CC(C8)CC(C9)C7)C%10%11CC%12CC(C%11)CC(C%12)C%10)Quality Control of Bis(2-(Di(adamantan-1-yl)phosphino)ethyl)amine, and with the development of science, more effects of this compound(1086138-36-4) can be discovered.
