Thus, 2-cyclopropyl-1-trifluoromethylbenzo[b]thiophenium triflate was prepared by reacting 1-cyclopropylethynyl-2-trifluoromethylsulfanylbenzene with trifluoromethanesulfonic acid. When Me 1-indanone-2-carboxylate was treated with 2-cyclopropyl-1-trifluoromethylbenzo[b]thiophenium triflate, 1-oxo-2-trifluoromethylindan-2-carboxylic acid Me ester was obtained. The experimental process involved the reaction of 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile(cas: 2510-01-2).Category: nitriles-buliding-blocks

And the article contained the following:

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. The experimental process involved the reaction of 2-Aminomalononitrile 4-methylbenzenesulfonate(cas: 5098-14-6).Safety of 2-Aminomalononitrile 4-methylbenzenesulfonate
