Fine chem. and pharmaceutical companies often employ reactive crystallization or precipitation to make crystalline intermediates and finished products. The supercritical reactive crystallization route was used for the precipitation of diverse metal-organic frameworks (MOFs). 1-dimensional and 2-dimensional MOFs were obtained by reacting either bipyridyl (two linking positions) or triazine (three linking positions)-based bridging mols., resp., with supercritical CO2 soluble M(hfacac)2 (M = Zn2+ or Cu2+ and hfacac– stands for hexafluoroacetylacetonate). Addnl., miscellaneous reactions were designed for the crystallization of 3-dimensional MOFs in scCO2, embracing the precipitation of MIL-88B(Fe), ZIF-8, and a new Zn2+-curcumin coordination polymer. Obtained crystals in each case were analyzed from a morphol. point of view by SEM anal. to elucidate potential formation mechanisms. The focus was on the obtained crystal habits at different reaction points, linked to the precipitation mode and the role of kinetic and thermodn. crystal growth control. The supercritical procedure led to the crystallization of stable hierarchical nanostructures with micro- and mesoporosity and the precipitation of nanocrystals. In the experiment, the researchers used many compounds, for example, copper(ii)hexafluor-2,4-pentanedionate (cas: 14781-45-4Recommanded Product: copper(ii)hexafluor-2,4-pentanedionate).
copper(ii)hexafluor-2,4-pentanedionate (cas: 14781-45-4) belongs to copper catalysts. The evolution of transition metal catalysts has attained a stage of civilization that authorizes for an extensive scope of chemical bonds formation partners to be combined efficiently. These ligands enable the reaction promoted in mild condition. The reaction scope has also been greatly expanded, rendering this copper-based cross-coupling attractive for both academia and industry.
