Bromination mechanisms of aromatic pollutants: formation of Br2 and bromine transfer from metallic oxybromides

A Multiconformational Transition State Theory Approach to OH Tropospheric Degradation of Fluorotelomer Aldehydes

“…Besides presenting the rate coefficients at a temperature of $${T = 298.15}$$ K, we have also considered a temperature interval relevant for atmospheric conditions in the troposphere, [7,9,12] namely $${230 \le T/{\rm{K}} \le 320}$$ . Following our previous work, [31] we have fitted the corresponding data to an Arrhenius‐Kooij equation [12,105,106] of the form $${k\left( T \right) = }$$ $${A{\rm{exp}}\left( { - B/T} \right)}$$ $${(T/298)^n }$$ .…”

“…FTALs are one of the degradation products [1–5] of fluorotelomer alcohols (FTOHs), which are a class of linear fluorinated alcohols with the formula C x F 2 x +1 CH 2 CH 2 OH, where x tends to be an even number as a consequence of the telomerization manufacturing process [6] . The degradation steps of FTOHs eventually lead [1,7] to the formation of perfluorinated carboxylic acids (with the general formula C x F 2 x +1 C(O)OH, which resist degradation via oxidation, hydrolysis, or reduction under biotic and abiotic conditions [8] and have or may have an immediate or long‐term harmful effect on the environment or its biological diversity [Ref. [2] and references therein].…”

Bringing Green Organic Electrochemistry to Undergraduates: A Designed Comparison Organic Experiment of Bromination

“…Traditional approaches of bromination of aromatic compounds could be broadly divided into two categories. One is using liquid bromine (Br 2 ) as bromine source under certain conditions; , the other is utilizing bromo-organic compounds, such as N -bromosuccinimide (NBS), 1,3-dibromo-5,5-dimethylhain (DBH), carbon tetrabromide, etc. , Several traditional synthetic schemes of bromination using NBS or liquid bromine are listed in Scheme b …”
