THE ELECTROLYSIS OF ω-BROMOCARBOXYLIC ACIDS

摘要: The first successful preparation of ω,ω′-dibromides from the electrolyses a series ω-bromocarboxylic acids, Br(CH2)nCOOH (n = 5 to n = 11), is reported. Under conditions fairly low temperature and current density, yields 54 71% these dibromides were obtained.The electrolysis 11-bromoundecanoic acid discussed as an example how small change in experimental can produce considerable products reaction. At 50°, product was mainly 1,20-dibromoeicosane, whereas at 65° esters methyl 11-bromoundecanoate 11-methoxyundecanoate.
