Hydroxylation of activated aromatic rings has been acheved by anodic substitution followed by hydrolysis. The nucleophiles employed are anions of trifluoroacetic acid andp-toluenesulphonic acid, which result in ring-deactivation upon monosubstitution and are easily hydrolysed. High yields at high substrate conversion for the electrochemical step were obtained in dry acetonitrile solutions by constant potential electrolysis at graphite or platinum anodes. Hydrogen evolution at a platinum cathode occurred in the same compartment. Preliminary experiments have shown that the electrolysis proceeds similarly in the presence of a second immiscible solvent (CCl4 or di-n-butyl ether). |
