The new anionic nickelate complexes [(MeCN)Ni(C4F8)(CF3)]–, [(MeCN)Ni(C4F8)(C2F5)]–, [(IMes)Ni(C4F8)(CF3)]–, [(IMes)Ni(CF3)3]– (IMes = 1,3-bis(2,4,6-trimethylphenyl)imidazol-2-ylidene), and [(F-NHC)Ni(Rf)3]– (F-NHC = 1,3-bis(2,4-F2Ph), 2,4,6-F3Ph- or 3,4,5-F3Ph)imidazol-2-ylidene; (Rf = CF3 or C2F5) were synthesized and structurally characterized. The electrochem. properties of all new compounds were revealed by cyclic voltammetry studies and compared to the known CF3 analog [(MeCN)Ni(CF3)3]–. The IMes-coordinated complexes exhibited initial oxidation events that were well-separated from a second oxidation process in the cyclic voltammograms. The complexes containing F-substituted NHC ligands [(F-NHC)Ni(CF3)3]– are structurally quite similar to the IMes derivative and reveal also two separated oxidation waves in their cyclic voltammograms. The absolute potentials as well as the separation between the two waves vary with the substitution pattern, suggesting that the NHC ligand environment (NHC = N-heterocyclic carbene) is an interesting platform for the development of new redox-triggered reactions that release trifluoromethyl and perfluoroalkyl radicals upon oxidation This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0Quality Control of Tetramethylammonium chloride).
Tetramethylammonium chloride (cas: 75-57-0) belongs to organic chlorides. Organic chlorides are compounds containing a carbon-chlorine bond, which are widely used in the oil field as a wax dissolver. Alkyl chlorides readily react with amines to give substituted amines. Alkyl chlorides are substituted by softer halides such as the iodide in the Finkelstein reaction.Quality Control of Tetramethylammonium chloride
