Bromination of 2,1,3-Benzothiadiazole [PDF]
, 2017 2,1,3-benzothiadiazole is widely used in conducting polymer research. 4,7-Dibromo-2,1,3-benzothiadiazole or 4-bromo-2,1,3-benzothiadiazole can be used for valuable blocks in the main-chain to improve electronic property of resultant polymers.

On the influence of carbon nanoparticles as additives in the electrosynthesis of bromoarenes
Carbon Trends, 2021 Kinetic studies on an electrochemical bromination reaction are presented. In the presence of different carbon nanoparticles bromide salts were used as safe bromine sources and the interplay of graphene derivates with different electrode materials was ...

Trace Level Arsenic Quantification through Methyl Red Bromination [PDF]
, 2012 A simple protocol has been developed for the quantification of trace level arsenic through methyl red bromination. The proposed method is based on the oxidation of arsenic(III) to arsenic(V) by the bromine and the residual bromine’s reaction with methyl ...

Synthesis of Breitfussin B by Late-Stage Bromination.
Organic Letters, 2015 The breitfussins are halogenated natural products whose structures were determined with the assistance of atomic-force microscopy. The site selectivity of N-bromosuccinimide-mediated bromination of a model breitfussin core was found to be strongly ...

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 ...

Preparation, aromaticity, and bromination of spiro iridafurans
, 2023 Iridium centers of [Ir(μ-Cl)(C8H14)2]2 (1) activate the Cβ(sp2)–H bond of benzylideneacetone to give [Ir(μ-Cl){κ2-C,O-[C(Ph)CHC(Me)O]}2]2 (2), which is the starting point for the preparation of the spiro iridafurans IrCl{κ2-C,O-[C(Ph)CHC(Me)O]}2(PiPr3 ...

Regioselective Monobromination of Phenols with KBr and ZnAl–BrO3−–Layered Double Hydroxides
Molecules, 2020 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
