silica nanospheres are prepared through the co-assembly of chiral (4-(trimethoxysilyl)ethyl)phenylsulfonyl-1,2-diphenylethylene-diamine and tetraethoxysilane followed by complexation with an organoruthenium complex. Structural analysis and characterization disclose its well-defined single-site organoruthenium active center, and electron microscopy images reveal its uniformly distributive, mesostructured

Ruthenium-Catalyzed One-Pot Tandem Isomerization-Transfer Hydrogenation Reactions of γ-Trifluoromethylated Allylic Alcohols and β-Trifluoromethylated Enones
transform γ‐trifluoromethylatedallylicalcohols and β‐trifluoromethylated enones into the corresponding saturated alcohols in excellent yields via a one‐pot tandem process involving isomerization and transfer hydrogenation(s). High stereospecificity was demonstrated and evidence for two mechanisticpathways is provided. The method was applied to a rapid synthesis of trifluoromethylated citronellol
