A selective reductive monodefluorination reaction of trifluoromethyl arenes was developed. Mediated by magnesium metal, various difluoromethylated aromatics were accessed at room temperature in the presence of acetic acid. This protocol shows tolerance to a wide range of functional groups and it was applicable in late-stage hydrodefluorination of complex pharmaceutical compounds, affording the corresponding CF2H analogues and their deuterated (CF2D) counterparts.
