General description

Tetrafluoro-1,4-benzoquinone is a fluorinated building block, commonly used as a precursor for fluoro derivatives.

application

Tetrafluoro-1,4-benzoquinone (fluoranil) can be used to prepare:
  • Symmetrical or unsymmetrical ethers by coupling of two alcohols via the oxidation-reduction condensation reaction.
  • Azocino[4,3-b]indole scaffold, which is used as an inetermediate to prepare (±)-dasycarpidone.
  • Chiral and racemic charge-transfer (CT) complexes with binaphthol.

We have shown previously that hydroxyl radicals (HO*) can be produced by H2O2 and halogenated quinones, independent of transition metal ions; however, the underlying molecular mechanism is still unclear. In the present study, using the electron spin resonance secondary radical
