An active site-isolated organoruthenium-/organopalladium-functionalized yolk–shell-structured mesoporous silica is developed and its application in the one-pot enantioselective tandem Sonogashira coupling–asymmetric transfer hydrogenation of haloacetophenones and arylacetylenes to various chiral conjugated alkynols is investigated.

A series of chiral complexes of the form Ir(NHC)2(aa)(H)(X) (NHC = N-heterocyclic carbene, aa = chelated amino acid, X = halide) was synthesized by oxidative addition of -amino acids to iridium(I) bis-NHC compounds and screened for asymmetric transfer hydrogenation of ketones. Following optimization of the reaction conditions, NHC, and amino acid ligands, high enantioselectivity was achieved when employing the Ir(IMe)2(l-Pro)(H)(I) catalyst (IMe = 1,3-dimethylimidazol-2-ylidene), which asymmetrically reduces a range of acetophenone derivatives in up to 95% enantiomeric excess.
