Allgemeine Beschreibung
2,4,4,6-Tetrabromo-2,5-cyclohexadienone forms solid charge-transfer molecular complexes with 4-(aminomethyl)piperidine and their spectroscopic characteristics were studied.
Anwendung
2,4,4,6-Tetrabromo-2,5-cyclohexadienone was used as catalyst for efficient deoxygenation of sulfoxides to their corresponding sulfides with 1,3-dithiane. It was also used as reagent for conversion of alcohols to azides.

Brominated flame retardants (BFRs) can enter aquatic environments where they can have adverse effects on organisms. The BFR, 1,2,5,6-Tetrabromocyclooctane (TBCO), has been introduced as a potential replacement for the major use BRF, Hexabromocyclododecane (HBCD). However, little is known about effects

The influence of natural organic matter (NOM) on the solid-phase extraction (SPE) efficiency was investigated for legacy and emerging flame retardants (FRs; n=26) in surface water. Three different groups of FRs were analyzed: polybrominated diphenyl ethers (PBDEs), halogenated flame retardants
