Trifluoroethylation : Aryl boronic acids can be catalytically trifluoroethylated with the readily available reagent CF 3 CH 2 I (see scheme, dba=dibenzylideneacetone). The reaction tolerates a variety of functional groups and can be extended to the trifluoroethylation of aryl or alkenyl boronic esters. The method is also suitable for the late‐stage installation of the CF 3 CH 2 group into target molecules.
