Usage

General Description

4,6-Dibromodibenzofuran is a chemical compound with the molecular formula C12H6Br2O. It is a dibenzofuran derivative that contains two bromine atoms. This chemical is a white solid that is sparingly soluble in water but soluble in organic solvents. 4,6-Dibromodibenzofuran is primarily used as an intermediate or building block in the synthesis of other organic compounds. It has been studied for its potential as a flame retardant additive due to its ability to inhibit the combustion of polymers. Additionally, it has been investigated for its potential use in organic electronic devices and as a building block in the synthesis of pharmaceuticals and agrochemicals. Due to its brominated structure, 4,6-Dibromodibenzofuran may pose environmental and health risks and should be handled and used with caution.

Cobalt corroles with phosphonic acid pendants as catalysts for oxygen and hydrogen evolution from neutral aqueous solution

Cobalt corroles with different acid/base pendants, LBr-Co, LCOOH-Co, LPO(OH)2-Co, and LCH2PO(OH)2-Co (L = 5,15-bis-(pentafluorophenyl)-10-(4-dibenzofuran)corrole), were synthesized and examined as catalysts for oxygen and hydrogen evolution from neutral aqueous solutions. Co corroles with phosphonic acid pendants showed improved activities in both processes, highlighting the importance of the secondary coordination sphere in catalyst design.

Mechanisms of dioxin formation from the high-temperature oxidation of 2-bromophenol

The homogeneous, gas-phase oxidative thermal degradation of 2-bromophenol was studied in a 1 cm i.d., fused silica flow reactor at a concentration of 88 ppm, reaction time of 2.0 s, over a temperature range from 300 to 1000 °C. Observed products in order of yield were dibenzo-p-dioxin (DD) > 4,6-dibromodibenzofuran (4,6-DBDF) > 4-monobromodibenzofuran (4-MCDF), dibenzofuran (DF), 1-monobromodibenzo-p-dioxin (1-MBDD), naphthalene, bromonaphthalene, 2,4-dibromophenol, 2,6-dibromophenol, phenol, bromobenzene, and benzene. This result is in contrast to the oxidation of 2-chlorophenol, where the major product is 4,6-dichlorodibenzofuran (4,6-DCDF). 4,6-DBDF was observed in high yields in contrast to our previous results for the pyrolysis of 2-bromophenol, where 4,6-DBDF was not detected. The increase in 4,6-DBDF yields is attributed to hydroxyl radical being the major chain carrier under oxidative conditions, which favors hydrogen-abstraction reactions that lead to formation of 4,6-DBDF. However, DD is still the highest yield product under oxidative conditions because of the relative ease of displacement of Br? in the ring-closure reaction.
