WebJan 26, 2009 · In general, bromonium salts are more reactive but have similar reaction behaviour [32, 36]. Thus they could be helpful substrates for the synthesis of N-arylcarbazoles from anilines. ...... WebApr 24, 2024 · It is demonstrated that the intrinsic reactivity of the bench-stable bromine(III) species can be unlocked by addition of a Lewis or a Brønsted acid. Abstract In sharp contrast to hypervalent iodine(III) compounds, the isoelectronic bromine(III) counterparts have been little studied to date.

WebThe rate of addition of bromine to alkenes is strongly affected by the degree of substitution of the C═C unit. Alkyl groups increase the rate of the reaction. The relative rates of addition of bromine to ethene, propene, and 2-methylpropene are 1, 60, and 5.5 × 10 3, respectively. Because alkyl groups can donate electrons and stabilize a ...
