要旨
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.
