Fluorinated molecules and particularly trifluoromethylated compounds are widely used in the pharmaceutical or agro- chemical fields, and much effort has been devoted to establish- ing improved methods for the introduction into organic substrates of fluoro or trifluoromethyl groups. The most common reactants used to achieve trifluromethyl- ation reactions1 are organometallic compounds, eg CF3Cu2 and CF3ZnX3 (X = CF3, Br, I etc.) or the Ruppert reactant ...
