Catalytic Hydrotrifluoromethylation of Unactivated Alkenes

A visible-light-mediated hydrotrifluoromethylation of unactivated alkenes that uses the Umemoto reagent as the CF₃ source and MeOH as the reductant is disclosed. This effective transformation operates at room temperature in the presence of 5 mol % Ru­(bpy)₃Cl₂; the process is characterized by its operational simplicity and functional group tolerance

Trifluoromethylation of Allylsilanes under Photoredox Catalysis

A new catalytic method to access allylic secondary CF₃ products is described. These reactions use the visible light excited Ru(bpy)₃Cl₂·6H₂O catalyst and the Togni or Umemoto reagent as the CF₃ source. The photoredox catalytic manifold delivers enantioenriched allylic trifluoromethylated products not accessible under Cu(I) catalysis
