In 2022,Inorganic Chemistry Frontiers included an article by Das, Rajesh; Parihar, Vaibhav; Nagaraja, C. M.. COA of Formula: C27H39ClN2. The article was titled 《Strategic design of a bifunctional Ag(I)-grafted NHC-MOF for efficient chemical fixation of CO2 from a dilute gas under ambient conditions》. The information in the text is summarized as follows:
The chem. fixation of carbon dioxide into valuable products constitutes a promising step toward reducing the atm. CO2 concentration Consequently, herein we report the strategic design of a bifunctional catalyst by grafting catalytically active Ag(I) ions onto N-heterocyclic carbene (NHC) sites in a MOF for efficient chem. fixation of CO2 from a dilute gas to oxazolidinones, bio-relevant commodity chems. Indeed, Ag(I)@MOF-NHC demonstrated excellent catalytic activity for efficient fixation of CO2 from a dilute gas (CO2 : N2 = 13 : 87%) with alkynes to afford valuable chems., oxazolidinones, under RT and atm. pressure (balloon) conditions. The superior activity of the Ag(I) anchored MOF over the individual (AgNO3 and MOF-NHC) components has been ascribed to the synergistic effect between the CO2-philic NHC and alkynophilic Ag(I) sites exposed in the 1D channels of the MOF. Furthermore, the Ag(I) anchored MOF showed high recyclability without significant loss of catalytic activity and structural rigidity. Overall, this is a unique demonstration of the utilization of dilute CO2 under environmentally friendly mild conditions and can pave the way for the development of efficient catalytic systems for sustainable utilization of CO2 from dilute gases. The results came from multiple reactions, including the reaction of 1,3-Bis(2,6-diisopropylphenyl)-4,5-dihydro-1H-imidazol-3-ium chloride(cas: 258278-25-0COA of Formula: C27H39ClN2)
1,3-Bis(2,6-diisopropylphenyl)-4,5-dihydro-1H-imidazol-3-ium chloride(cas: 258278-25-0) has been employed in an efficient, one-pot synthesis of N-heterocyclic carbene-allylpalladium complexes.COA of Formula: C27H39ClN2In addition, it can efficiently catalyze the Suzuki-Miyaura coupling of aryl chlorides with aryl boronic acids.
