New Ni-containing ionic liquids were synthesized, characterized and their electrochem. was studied. A mechanism for the electrochem. synthesis of nanoparticles from these compounds is proposed. In these so-called liquid metal salts, the Ni(II) cation is octahedrally coordinated by six N-alkylimidazole ligands. The different counteranions that were used are bis(trifluoromethanesulfonyl)imide (Tf2N–), trifluoromethanesulfonate (OTf–) and methanesulfonate (OMs–). Several different N-alkylimidazoles were considered, with the alkyl side-chain ranging in length from Me to dodecyl. The newly synthesized liquid metal salts were characterized by CHN anal., FTIR, DSC, TGA and viscosity measurements. An odd-even effect was observed for the melting temperatures and viscosities of the ionic liquids, with the complexes with an even number of C atoms in the alkyl chain of the imidazole having a higher melting temperature and a lower viscosity than the complexes with an odd number of carbons. The crystal structures of several of the Ni(II) complexes that are not liquid at room temperature were determined The electrochem. of the compounds with the lowest viscosities was studied. The Ni(II) cation could be reduced, but surprisingly no Ni deposits were obtained on the electrode. Instead, Ni nanoparticles were formed at 100% selectivity, as confirmed by TEM. The magnetic properties of these nanoparticles were studied by SQUID measurements. In the experiment, the researchers used many compounds, for example, 1-Octyl-1H-imidazole (cas: 21252-69-7Synthetic Route of C11H20N2).
1-Octyl-1H-imidazole (cas: 21252-69-7) belongs to imidazole derivatives. Many natural products, especially alkaloids, contain the imidazole ring. These imidazoles share the 1,3-C3N2 ring but feature varied substituents. The pharmacophore of imidazole exists in bioactive compounds including amino acids, plant growth regulators and therapeutic agents.n increase of the alkyl chain length of the alcohols.
