Verwenden
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.
Allgemeine Beschreibung
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.
läuterung methode
Recrystallise it twice from 95% EtOH to give yellow needles [Beck et al. J Am Chem Soc 108 4018 1986]. The dioxime has m 278o(dec). [Beilstein 7 H 632, 7 I 346, 7 II 580, 7 III 3376, 7 IV 2081.]
