Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. In an article, author is Lim, Jaewoong, once mentioned the application of 206996-60-3, Name is Cerium(III) acetate xhydrate, molecular formula is C6H11CeO7, molecular weight is 335.2633, MDL number is MFCD00150533, category is catalyst-ligand. Now introduce a scientific discovery about this category, Quality Control of Cerium(III) acetate xhydrate.
Amine-Tagged Fragmented Ligand Installation for Covalent Modification of MOF-74
MOF-74 is one of the most explored metal-organic frameworks (MOFs), but its functionalization is limited to the dative post-synthetic modification (PSM) of the monodentate solvent site. Owing to the nature of the organic ligand and framework structure of MOF-74, the covalent PSM of MOF-74 is very demanding. Herein, we report, for the first time, the covalent PSM of amine-tagged defective Ni-MOF-74, which is prepared by de novo solvothermal synthesis by using aminosalicylic acid as a functionalized fragmented organic ligand. The covalent PSM of the amino group generates metal binding sites, and subsequent post-synthetic metalation with Pd-II ions affords the Pd-II-incorporated Ni-MOF-74 catalyst. This catalyst exhibits highly efficient, size-selective, and recyclable catalytic activity for the Suzuki-Miyaura cross-coupling reaction. This strategy is also useful for the covalent modification of amine-tagged defective Ni-2(DOBPDC), an expanded analogue of MOF-74.
