Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. , HPLC of Formula: C10H12O, 937-30-4, Name is 4-Ethylacetophenone, molecular formula is C10H12O, belongs to chiral-nitrogen-ligands compound. In a document, author is Fan, Yamei, introduce the new discover.
A Ni(salen)-Based Metal-Organic Framework: Synthesis, Structure, and Catalytic Performance for CO2 Cycloaddition with Epoxides
A three-dimensional (3D) chiral metal-organic framework [Cd-2{Ni(salen)}(DMF)(3)]4 center dot DMF center dot 7H(2)O (1) based on a new enantiopure tetracarboxyl-functionalized metallosalen Ni(H(4)salen) {where H(6)salen is (R,R)-N,N-bis[3-tert-butyl-5-(3,5-dicarboxybenzyl)salicylidene]-1,2-diphenylethylenediame} was synthesized and characterized by infrared spectroscopy, thermogravimetric analysis, nitrogen and carbon dioxide adsorption, and powder and single-crystal X-ray diffractions. In 1, the dinuclear Cd-2 cluster [Cd-2(COO)(4)(DMF)(3)] as a node is cross-linked by four isophthalate groups on the salen ligands, forming a 2D lamellar structure, which are further linked by Ni(salen) into the 3D network with a 1D open channel (ca. 7.0 x 8.0 angstrom(2)) along the a axis. On account of its porosity, Lewis acid sites, and moderate uptake for CO2, 1 can be used as an efficient heterogeneous catalyst for the CO2 cycloaddition with epoxides under relatively mild conditions. Moreover, the bulky epoxide shows a decrease in activity with an increase in the alkyl chain length of the substrate as a result of the confinement effect of 1, showing size-dependent selectivity.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 937-30-4. HPLC of Formula: C10H12O.
