Synthetic Route of 652-12-0, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 652-12-0, molcular formula is C8F4O3, introducing its new discovery.
Some tricyclohexyltin(IV) carboxylates, HOOC-R-COOSn(c-C6H 11)3 (1) and (c-C6H11) 3SnOOC-R-COOSn(c-C6H11)3 (2) [R = 1,2-C6H4 (a), 1,2-C6F4 (b), (Z)-CH=CH (c), CH2CH2 (d)], have been synthesized from reaction of tricyclohexyltin hydroxide with cyclic dicarboxylic anhydrides under microwave irradiation in 1: 1 and 2: 1 M ratio, respectively, and characterized by elemental analysis, IR and NMR (1H, 13C, and 119Sn) spectra. Crystal structures of 1a-1c and 2d are determined by X-ray single crystal diffraction. The carboxylate in each compound is monodentate to tin. Compounds 1a and 1c possess a trans-C3SnO 2 trigonal bipyramidal geometry with axial positions occupied by carboxylate and carbonyl oxygen of carboxylate of an adjacent molecule forming a one-dimensional chain. Compound 1b is tetrahedral and forms R 2 2(8) hydrogen-bonded dimers by pairs of intermolecular O-H O hydrogen bonds between two carboxylic acid groups. Compound 2d is dinuclear with tin possessing distorted tetrahedral geometry; a trimer supramolecular structure is formed by weak intermolecular Sn O interactions. The compounds have potent in vitro cytotoxic activity against two human tumor cell lines, A549 and HeLa.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 652-12-0 is helpful to your research. Synthetic Route of 652-12-0
