General description
2,5-Dichloro-1,4-benzoquinone (DCBQ) is a halogenated quinone. DCBQs are carcinogenic intermediates.They have benn identified as chlorination disinfection byproducts in drinking water. DCBQ has been reported to increse the decomposition of a model ROOH tert-butylhydroperoxide, via formation of t-butoxyl radicals. The isomers of the DCBQ dimer have been investigated for the non-covalent interactions (NCIs) by quantum chemical calculations. Halogen bond present in 2,5-dichloro-1,4-benzoquinone have been investigated by experimental as well as theoretical charge density analysis. Its reaction with pyrrolidine has been investigated.
Application
2,5-Dichloro-1,4-benzoquinone may be used in the following processes:
- As a starting material in the synthesis of asterriquinone D.
- As a model to study the utility of a novel photoreactor with LED (light-emitting diode) light source and a fibre-optic CCD (charge-coupled device) spectrophotometer.
- 2,5-dichloro-3,6-bi(3-indolyl)-1,4-hydroquinone synthesis by palladium catalyzed reaction with indole.
