Schafer, Thomas C.; Becker, Jonathan; Seuffert, Marcel T.; Heuler, Dominik; Sedykh, Alexander E.; Mueller-Buschbaum, Klaus published an article in 2022. The article was titled 《Iodine-Chemisorption, Interpenetration and Polycatenation: Cationic MOFs and CPs from Group 13 Metal Halides and Di-Pyridyl-Linkers》, and you may find the article in Chemistry – A European Journal.Category: bromides-buliding-blocks The information in the text is summarized as follows:
Eight cationic, two-dimensional metal-organic frameworks (MOFs) were synthesized in reactions of the group 13 metal halides AlBr3, AlI3, GaBr3, InBr3 and InI3 with the dipyridyl ligands 1,2-di(4-pyridyl)ethylene (bpe), 1,2-di(4-pyridyl)ethane (bpa) and 4,4′-bipyridine (bipy). Seven of them follow the general formula 2∞[MX2(L)2]A, M = Al, In, X = Br, I, A-=[MX4]-, I-, I3-, L = bipy, bpa, bpe. Thereby, the porosity of the cationic frameworks can be used to take up the heavy mol. iodine in gas-phase chemisorption vital for the capture of iodine radioisotopes. This is achieved by switching between I- and the polyiodide I3- in the cavities at room temperature, including single-crystal-to-single-crystal transformation. The MOFs are 2-dimensional networks that exhibit (4,4)-topol. in general or (6,3)-topol. for 2∞[(GaBr2)2(bpa)5][GaBr4]2·bpa. The two-dimensional networks can either be arranged to an inclined interpenetration of the cationic two-dimensional networks, or to stacked networks without interpenetration. Interpenetration is accompanied by polycatenation. Due to the cationic character, the MOFs require the counterions [MX4]-, I- or I3- counterions in their pores. Whereas the [MX4]-, ions are immobile, iodide allows for chemisorption. Also, eight addnl. coordination polymers and complexes were identified and isolated that elaborate the reaction space of the herein reported syntheses. In the part of experimental materials, we found many familiar compounds, such as Indium(III) bromide(cas: 13465-09-3Category: bromides-buliding-blocks)
Indium(III) bromide(cas: 13465-09-3) is used in organic synthesis as a water tolerant Lewis acid. It efficiently catalyzes the three-component coupling of β-keto esters, aldehydes and urea (or thiourea) to afford the corresponding dihydropyrimidinones.Category: bromides-buliding-blocks
