Bromine-Promoted One-Pot Furo[b]annulation and α‑C(sp²)‑Thiomethylation Cascade of (E)‑3-Styrylquinoxalin-2(1H)‑ones with Dimethyl Sulfoxide

, 2022
A new process has been developed for the bromine-promoted sequential (sp2)C = (sp2)C bond functionalization of (E)-3-styrylquinoxalin-2(1H)-ones and furo[b]annulation via the 5-exo-cyclization in dimethyl sulfoxide (DMSO). The reaction represents a novel

Determination of Bromine in Brine by Wavelength Dispersive X-ray Fluorescence Spectrometry with Film Adsorption Pretreatment

Yankuang ceshi, 2015
Bromine exists mainly as ions in bromide brine and halide sulfate brine in the hydrosphere of the crust. Powder carrier pellet method is commonly used in analyzing bromine in brine by Wavelength Dispersive X-ray Fluorescence Spectrometry (WDXRF). However,

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 ...

(C5H12N)Cu2Br3: A Piperidinium Copper(I) Bromide with [Cu2Br3]− Ladders

Crystals, 2012
Piperidinium copper(I) bromide, (C5H12N)Cu2Br3, was obtained from a solution of CuBr2, piperidine, and HBr in ethanol. At 60 °C ethanol slowly reduces copper(II) to copper(I).

Short-lived brominated hydrocarbons – observations in the source regions and the tropical tropopause layer [PDF]

, 2011
We conducted measurements of the five important short-lived organic bromine species in the marine boundary layer (MBL). Measurements were made in the Northern Hemisphere mid-latitudes (Sylt Island, North Sea) in June 2009 and in the tropical Western ...
