    摘要: Provided is a reaction reagent for trifluoromethylation with high general versatility and good efficiency.
    The reaction reagent for trifluoromethylation contains an iron compound, trifluoromethyl iodide, a sulfoxide and a peroxide, and may further contain an acid. The iron compound is, for example, iron(II) sulfate, ammonium iron(II) sulfate, iron(II) tetrafluoroborate, ferrocene, bis(η 5 -pentamethylcyclopentadienyl)iron or an iron powder; the sulfoxide is, for example, dimethyl sulfoxide; the peroxide is, for example, hydrogen peroxide or hydrogen peroxide-urea composite; and the acid is, for example, sulfuric acid, tetrafluoroboric acid or trifluoromethanesulfonic acid.
