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)(3)Cl-2 center dot 6H(2)O 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.
