Non-catalytic bromination of benzene: a combined computational and experimental study [PDF]

, 2015
The non-catalytic bromination of benzene is shown experimentally to require high 5-14M concentrations of bromine in order to proceed at ambient temperatures to form predominantly bromobenzene, along with detectable (The non-catalytic bromination of ...

Asymmetric synthesis of gonytolide A: strategic use of an aryl halide blocking group for oxidative coupling [PDF]

, 2018
The first synthesis of the chromanone lactone dimer gonytolide A has been achieved employing vanadium(V)-mediated oxidative coupling of the monomer gonytolide C. An o-bromine blocking group strategy was employed to favor para- para coupling and to enable

Regioselective bromination: Synthesis of brominated methoxyquinolines

Tetrahedron, 2017
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 ...

Direct Vapor-Phase Bromination of Multiwall Carbon Nanotubes

Journal of Nanotechnology, 2012
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.
