General description

Tetrachloro-1,4-benzoquinone (TCBQ) is a quinone compound with four chloride groups. The catalytic activity of quinone groups (benzoquinone) can be controlled by the chloride groups with large electronegativity.

Application

Synthesis of dibenzofurans via oxidative cyclization.
TCBQ can form a nanocomposite with multi-walled carbon nanotubes (MWCNTs) on a graphite electrode for nicotinamide adenine dinucleotide (NADH) oxidation. It can also provide pseudocapacitance and can be used as an electrode material for the development of supercapacitors. It may be used as an organic cathode and act as a redox mediator for the fabrication of lithium ion batteries.
Undergoes photoinduced cycloaddition reactions with stilbene derivatives and α,β-unsaturated carbonyl compounds. Fluorescence quencher.
