Meyer, Tim; Konrath, Robert; Kamer, Paul C. J.; Wu, Xiao-Feng published the article 《Pincer Ligand Enhanced Rhodium-Catalyzed Carbonylation of Formaldehyde: Direct Ethylene Glycol Production》. Keywords: rhodium formaldehyde ethylene glycol carbonylation catalyst.They researched the compound: Bis(2-(Di(adamantan-1-yl)phosphino)ethyl)amine( cas:1086138-36-4 ).Formula: C44H69NP2. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:1086138-36-4) here.
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%.
After consulting a lot of data, we found that this compound(1086138-36-4)Formula: C44H69NP2 can be used in many types of reactions. And in most cases, this compound has more advantages.
