Abstract: An efficient solvent-free synthesis of a new family of functionalized chiral ionic liquids based on pyridinium cation has been developed from low-cost chiral terpenoid alcohols. An exhaustive characterization was performed using state-of-the-art

, p. 41 - 45 (2015/06/08)
P-Stereogenic PNP type pincer iridium complexes PNPtBuMeIrH2Cl (3) and PNPtBuMeIrH3 (4) were synthesized in reasonable yields and characterized by 1H NMR, 13C NMR, 31P NMR, HRMS and/or single crystal X-ray diffraction. The ORTEP diagram shows that the coordination geometry around the iridium center of complex 3 is approximately octahedral. The chlorinated iridium complex (3) and/or the trihydride iridium complex (4) were used as catalysts in the asymmetric hydrogenation of ketones, olefins and quinoline to provide the desired products with up to 17% enantioselectivity.

scheme or table, p. 155 - 158 (2012/01/03)
Chiral N,N′-dialkylated cyclohexanediamine derived ligands have been synthesized and used in the asymmetric hydrogenation of aryl ketones. Optically active alcohols with up to 90% enantiomeric excess were obtained in high yields.
