A general, ideal atom utilization electrochemical technology to enable alkene alkoxyhalogenation and organohalide dehalogenation in one pot is presented. This technology is highlighted by convergent strategy integrating several reactions, such as alkene alkoxyhalogenation, organohalide dehalogenation, and dehalogenation deuteration. Experimental data suggest that alkenes have the lowest oxidation potential, which lead to anodic conversion of the C═C bond to the radical cation intermediates, and cathodic transformations of organohalides, including alkyl and aryl halides, as the nucleophilic halogen sources.

Paragraph 0048; 0049, (2019/02/26)
The invention discloses a synthesizing method of a beta-bromo ether compound. The method specifically comprises the following steps: mixing a styrene compound which is as shown in formula I and is taken as a raw material, bromate intercalated zn-al hydrotalcite ZnAl-BrO3-LDHs and an alkali metal bromide compound; dissolving in an organic solvent; reacting for 1-4h at the temperature of 15-60 DEG C under the action of organic acid; obtaining a reaction solution after the reaction is finished; and separating and purifying to obtain the beta-bromo ether compound as shown in formula II. The method has the advantages of being high in bromine source stability, simple, easy to obtain, mild in reaction conditions, environmentally friendly, simple to operate and the like.

A mild, efficient, and highly regio- and stereoselective method for the methoxy and ethoxy bromination of olefins has been developed using NH 4Br as a bromine source and Oxone as an oxidant. Various kinds of olefins (aromatic, linear, and cyclic olefins) afforded the corresponding alkoxy brominated products in moderate to excellent yields. Taylor & Francis Group, LLC.
Comparative study of the vicinal functionalization of olefins with 2:1 bromide/bromate and iodide/iodate reagents
Agrawal, Manoj K.,Adimurthy, Subbarayappa,Ganguly, Bishwajit,Ghosh, Pushpito K.
experimental part, p. 2791 - 2797 (2009/08/08)
A comparative evaluation was made on the syntheses of vicinal halohydrins, halo methyl ethers, and halo acetates from olefins using 2:1 Br-/BrO3- and I-/IO3- reagents. In many cases both reagents afforded products selectively in high yields. The highest halogen atom efficiencies attained were 97% and 93% for Br-/BrO3- and I-/IO3-, respectively. Of the two reagents, I-/IO3- was established to be the preferred reagent for vicinal functionalization of linear alkenes and also for halo acetate preparation. However, only Br-/BrO3- was effective for vicinal functionalization of trans-stilbene and chalcones.
