[Bis(trifluoroacetoxy)iodo]benzene(Cas 2712-78-9) Usage

Purification Methods

Crystallise the iodo compound from warm trifluoroacetic acid and dry it over NaOH pellets. Recrystallise it also from Me2CO/pet ether. Its melting point depends on the heating rate. [Spyroudis & Varvoglis Synthesis 445 1975, application: Almond et al. Org Synth 66 132 1988.]

General Description

[Bis(trifluoroacetoxy)iodo]benzene (PIFA) is a hypervalent iodine(III) reagent widely used in organic synthesis for oxidative transformations, including intramolecular cyclizations, oxidative couplings, and decarboxylative alkylations. It serves as a versatile oxidant under mild conditions, enabling selective reactions such as the formation of azacarbocyclic spirodienones, oxidative dimerization of thiophenes, and metal-free C–H functionalizations. Its reactivity is often enhanced by additives like BF3·Et2O or photocatalysts, facilitating efficient bond formations without heavy metals. PIFA is particularly valued for its ability to generate radical intermediates and its compatibility with complex substrates, making it useful in pharmaceutical and materials chemistry.
