So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Meyer, Tim; Konrath, Robert; Kamer, Paul C. J.; Wu, Xiao-Feng researched the compound: Bis(2-(Di(adamantan-1-yl)phosphino)ethyl)amine( cas:1086138-36-4 ).Formula: C44H69NP2.They published the article 《Pincer Ligand Enhanced Rhodium-Catalyzed Carbonylation of Formaldehyde: Direct Ethylene Glycol Production》 about this compound( cas:1086138-36-4 ) in Asian Journal of Organic Chemistry. Keywords: rhodium formaldehyde ethylene glycol carbonylation catalyst. We’ll tell you more about this compound (cas:1086138-36-4).
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%.
In some applications, this compound(1086138-36-4)Formula: C44H69NP2 is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
