Rhodium catalyzed hydroformylation of α -methylstyrene was investigated in the presence of monodentate phosphine ligands L1 – L6 . We found that the phosphine with good π -acceptability could efficiently improve the activity of the α -methylstyr

A heterogeneous iridium catalyst was synthesized with silica particles as support for the hydrogenation of heteroaromatic methyl ketones. The catalyst and support were characterized by solid-state NMR, HTEM, SEM, XPS, and BET. A series of heteroaroma

High performance liquid chromatography (HPLC) and high speed counter-current chromatography (HSCCC) were applied and compared in enantioseparation of 2-phenylpropionic acid (2-PPA) when hydroxypropyl-β-cyclodextrin (HP-β-CD) was used as chiral mobi

Counter-current chromatography (CCC) was applied for preparative enantioseparation of three β-blocker drugs, including propranolol, pindolol and alprenolol. The two-phase solvent system was composed of chloroform-0.05 mol L(-1) acetate buffer contai
