Electrooxidation of 2,4,6‐tribromophenol on platinum gauze electrode in 90 % (v/v) alcohol (methanol, ethanol, propan‐1‐ol, butan‐1‐ol) was studied. Products were investigated by gas chromatography/mass spectrometry. Structures of several different types of monomeric as well as dimeric alkoxy derivatives have been suggested according to mass spectra of the detected products. Series of 2,6‐dibromo‐4‐alkoxyphenols, 2,4,6‐tribromo‐6‐alkoxycyclohexa‐2,4‐dien‐1‐ones and 2,6‐dibromo‐6‐alkoxycyclohex‐2‐ene‐1,4‐diones were found. By analogy to identified monomeric alkoxy derivatives, a serie of dimeric 2,6‐dibromo‐4‐(2,6‐dibromo‐4‐alkoxyphenoxy)phenols was suggested and identified in respective chromatograms as well.
