Regioselective bromination: Synthesis of brominated methoxyquinolines
Abstract Simple synthetic methods are described for the synthesis of valuable polyfunctional brominated methoxyquinolines 10–13, 20–21, and 24–25. Three regioselective routes are described for convenient preparation of brominated methoxyquinolines at the C-2, C-3, and C-5 positions with consecutive reaction steps under mild reaction conditions using ...

Regioselective Monobromination of Phenols with KBr and ZnAl–BrO3−–Layered Double Hydroxides
The regioselective mono-bromination of phenols has been successfully developed with KBr and ZnAl−BrO3−−layered double hydroxides (abbreviated as ZnAl−BrO3−−LDHs) as brominating reagents. The para site is much favorable

Direct Vapor-Phase Bromination of Multiwall Carbon Nanotubes
We present the simple procedure of the vapor-phase bromination of multiwall carbon nanotubes (MWNTs) at moderate temperatures. MWNTs with average diameter 9±3 nm were treated with Br2 vapors at 250°C to produce Br-functionalized product.

Bromination of hydrocarbons with CBr4, initiated by light-emitting diode irradiation
The bromination of hydrocarbons with CBr4 as a bromine source, induced by light-emitting diode (LED) irradiation, has been developed. Monobromides were synthesized with high efficiency without the need for any additives, catalysts, heating, or inert ...
