Bromohydrins and their ethers were electrochemically synthesized via hydroxy- and alkoxybromination of alkenes using potassium bromide and water or alcohols. High selectivity of bromohydrins formation was achieved only with the use of DMSO as the solvent and an acid as the additive. The proposed combination of starting reagents, additives, and solvents allowed to form bromohydrins or their ethers selectively despite the variety of side-products (epoxides, dibromides, diols). Bromohydrins were obtained in high yields, up to 96%, with a broad substrate scope in an undivided electrochemical cell equipped with glassy carbon and platinum electrodes at high current density.

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.

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.
