DibenzofuranElectrophilic brominationPBDFsDibenzofuran has been brominated under standard electrophilic conditions to yield mono- through octabromodibenzofuran. The GC retention indices for ten products have been measured and correlated with the retention indices for the corresponding chloro dibenzofurans. Mass ...
Based upon the current availability of [ 13C]-labeled dibenzo-p-dioxin and dibenzofuran (DD/DF) precursors, we have developed a simple and efficient synthetic procedure which produces brominated congeners that are predominantly substituted in the 2,3,7, and 8-positions. The gas/solid reaction ...
Context: This study delves into hole-electron transport and distribution properties inherent in mono-brominated dibenzofuran (DBF) and dibenzothiophene (DBT) isomers. As determined by frontier molecular orbitals, all brominated structures have narrower bandgaps than their primary structures. The TD-DFT ...
Controlling the emission of polybrominated dibenzo-p-dioxins and dibenzofurans (PBDD/Fs) presents a hugechallenge in the thermo-chemical conversion of halogenated waste. It is crucial to understand the formation ofPBDD/Fs to effectively control their emissions. This paper utilizes density functional ...
In contrast, when the electronic effect of the substituted groups is reversed, only the benzylic bromination products are gained. Based on this methodology, several potential AChE inhibitors, such as 2-methoxy-5-(benzylamino)mefhyl-dibenzofuran, 3-bromo-2-methoxy-5-met-hyl-9H-carbazole, 3,6...
