Phan, Nam T. S. published the artcileLigand-Free Copper-Catalyzed Coupling of Phenols with Nitroarenes by using a Metal-Organic Framework as a Robust and Recoverable Catalyst, Quality Control of 61343-99-5, the main research area is phenol coupling nitroarene copper metal organic framework catalyst; ligand free copper metal organic framework catalyst coupling reaction.
A highly porous metal-organic framework Cu2(BDC)2(DABCO) (H2BDC = 1,4-benzenedicarboxylic acid, DABCO = 1,4-diazabicyclo[2.2.2]octane) was synthesized and used as an efficient recyclable heterogeneous catalyst for the coupling reaction of phenols with nitroarenes to form diaryl ethers without using a ligand. Phys. characterization of the MOF was obtained by using XRD, SEM, TEM, thermogravimetric anal. (TGA), FTIR spectroscopy, at. absorption spectrophotometry (AAS), H2 temperature-programmed reduction (H2-TPR), and N2 physisorption measurements. The Cu2(BDC)2(DABCO)-catalyzed coupling reaction offers several advantages compared to the conventional Ullmann reaction for the synthesis of unsym. diaryl ethers. To the best of our knowledge, the ligand-free Cu-catalyzed O-arylation reaction of phenols with nitroarenes that uses a heterogeneous catalyst has not been mentioned previously in the literature.
