Acid-catalysed transformation of hexamethylazoxybenzene. An unusual product in the Wallach rearrangement
Abstract
2,2′,4,4′,6,6′-Hexamethylazoxybenzene reacts in strong sulphuric acid media to yield 4-hydroxymethyl-2,2′,4′,6,6′-pentamethylazobenzene; a reaction pathway for this novel process is suggested.
