Novel PCP-IrI monochloride complexes [[(1,3-tBu2PCH2)2BzIm]IrCl] (1-Cl, BzIm-H2 = 2-benzimidazolylidene) and [[(1,3-tBu2PCH2CH2)2Im]IrCl] (2-Cl, Im-H2 = 2-imidazolylidene) bearing a phosphine-carbene-phosphine pincer type ligand were synthesized. Reactions of 1-Cl with hexachloroethane, hydrogen chloride, and lithium triethylborohydride under a dihydrogen atm. afforded PCIIP-IrIII trichloride (1-Cl3), hydride dichloride (1-HCl2), and trihydride (1-H3) complexes, resp. The strong electron-donating ability of carbene in PCIIP-Ir complexes was confirmed by X-ray crystallog. and DFT calculations Moreover, in complex 1-Cl, strong π back-donation from the iridium center to the carbene carbon was observed Hydrogenation of CO2 with triethanolamine catalyzed by PCIIP-Ir complexes was investigated. The novel PCIIP-Ir complex 1-Cl exhibited a longer lifetime in comparison to the PNP-IrIII complex [(Ph2PCH2)2PyIrH3] (3-H3): the turnover number of 1-Cl is significantly higher than that of 3-H3 (in 46 h, 1-Cl 230000 and 3-H3 54000). In the experiment, the researchers used many compounds, for example, Chlorobis(ethylene)iridium(I) dimer (cas: 39722-81-1Product Details of 39722-81-1).
Chlorobis(ethylene)iridium(I) dimer (cas: 39722-81-1) 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. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Product Details of 39722-81-1
