Nikseresht, Ahmad published the artcile[Cu3(BTC)2]: A metal-organic framework as an environment-friendly and economically catalyst for the synthesis of tacrine analogues by Friedlaender reaction under conventional and ultrasound irradiation, Recommanded Product: 2-Aminomalononitrile 4-methylbenzenesulfonate, the publication is Polyhedron (2018), 112-117, database is CAplus.
Using a green and simple route with ultrasound illumination, atm. pressure and room temperature, for synthesizing tacrine analogs in the presence of [Cu3(BTC)2] as an environment-friendly and economically catalyst was considered. [Cu3(BTC)2] is one of the heterogeneous catalysts on hand capable of being employed, in the Friedlaender reaction, whenever 5-amino-4-cyano-2-phenyl-1,3-oxazole and appropriately substituted carbonyl derivatives under conventional and ultrasonic irradiation The results of this study indicate that the active sites in the [Cu3(BTC)2] for synthesis of cyclohepta[b]oxazolo[4,5-e]pyridine are mainly copper atoms and the role of Bronsted acid organic ligand in the MOF is negligible. These procedures were properly arranged to provide the utmost yields in a short while. The crystal stability in the process of catalysis was studied by various techniques such as XRD, BET and ICP that demonstrate excellent stability in reaction conditions.
