Mercury(II) chloride efficiently activates magnesium metal to induce a desulfonylative trifluoromethylation process. The new reductive trifluoromethylation provides an alternative method for efficient trifluoromethylation of non-enolizable or enolizable aldehydes with readily available phenyl trifluoromethyl sulfone reagent.
