Radical trifluoromethylation of aryl N,N-dimethyl hydrazones using TBAI as an initiator and Togni's reagent as a trifluoromethyl radical source is described. Cascades proceed via electron-catalysis; this approach is generally more applicable to hydrazone perfluoroalkylation using perfluoroalkyl iodides as the radical precursors in combination with a base under visible-light initiation.

Mild and practical: Trifluoromethylation of (hetero)aromatic aldehyde N,N-dialkylhydrazones was achieved at room temperature by using Togni's trifluoromethylation reagent under CuCl catalysis (see scheme). This simple reaction is believed to occur by a CF3-radical-transfer mechanism and yields useful trifluoromethylated building blocks. Copyright
