Chemical Properties

slightly brown powder with a pungent odour

Uses

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.
