Aromatic Bromination versus Oxidation of Indolylmalonates by Bromine
The Journal of Organic Chemistry, 2002The reactions of 5-substituted indolylmalonates (2a-e), carrying an electron-withdrawing group at the N(1) position, with bromine in CCl(4) or AcOH are reported. These substrates undergo oxidation in competition with the well-known aromatic bromination.

The reaction of bromine azide with bromine
Polyhedron, 1997Abstract The reactivity of bromine azide, BrN3, towards elemental bromine, Br2, was studied experimentally in the gas phase and in CH2Cl2 solution. The gas phase IR spectra of a 1:10 mixture of BrN3 and Br2 are in accord with the formation of small amounts of nitrogen tribromide, NBr3 but it was not possible to isolate the NBr3 from the reaction ...

SummaryA brief history of the measurement of diffusion of gases (excluding “effusion,” “transpiration,” and other processes from which data for the calculation of the diffusion coefficient may be obtained) is given.A visual method of following the diffusion of a strongly coloured vapour (bromine) into colourless gases is described.The diffusion ...

Bromination of 2-bromobenzobarrelene
Tetrahedron Letters, 1990Abstract Bromination of 2-bromobenzobarrelene 1 has been studied. Five bromine addition products 5, 6, 7, 8, and 9 have been isolated whose structural assignments were made on the basis of 1H-,13C-NMR spectral data and X-ray structural analysis. The formation of the rearranged product has been discussed in terms of Wagner-Meerwein rearrangement.

Bromination of pyridines. II. Bromination of Aminopicolines
Journal für Praktische Chemie, 1989AbstractThe bromination of all ten possible aminopicolines 1–10 was investigated. In general, the major brominated product was that corresponding to electrophilic attack at the sites para or ortho to the amino group.
