The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: Bis(2-(Di(adamantan-1-yl)phosphino)ethyl)amine( cas:1086138-36-4 ) is researched.Product Details of 1086138-36-4.Han, Zhaobin; Rong, Liangce; Wu, Jiang; Zhang, Lei; Wang, Zheng; Ding, Kuiling published the article 《Catalytic Hydrogenation of Cyclic Carbonates: A Practical Approach from CO2 and Epoxides to Methanol and Diols》 about this compound( cas:1086138-36-4 ) in Angewandte Chemie, International Edition. Keywords: catalytic hydrogenation cyclic carbonate methanol diol production. Let’s learn more about this compound (cas:1086138-36-4).
A highly efficient catalytic hydrogenation of cyclic carbonates was developed for the preparation of methanol with the cogeneration of the corresponding diols by using (PNP) Ru”” pincer complexes as the catalysts under relatively mild conditions. This process has provided a facile approach for the simultaneous production of two important bulk chems., methanol and EG, from ethylene carbonate, which is industrially available by reacting ethylene oxide with CO2. The coupling of the present catalytic system with the process of ethylene carbonate production in the omega process is expected to establish a new bridge from CO2 and ethylene oxide to methanol and EG. Apart from the clean production of diol, a big bonus of the present protocol is the efficient chem. utilization of CO2, which represents a distinct advantage in terms of sustainability over the omega process, which gives back CO2. Moreover, this catalytic system has also provided a potential process for the utilization of waste poly(propylene carbonate) as a resource to afford 1,2-propylene diol and methanol through hydrogenative depolymerization, and a convenient method for the preparation of deuterated methanol from CO2 and D2. A possible catalytic mechanism is proposed, in which the NH moiety of the ligand is demonstrated to be critically important in facilitating the reduction of the carbonate C=O bond through secondary coordination sphere interactions with substrates.
