<p>Pyrogallol, and analogues thereof having an alkyl, carboxy or alkoxycarbonyl substituent in the benzene ring, and their salts, are prepared by oxidising, preferably by hydrogen peroxide, the corresponding compounds in which 1 or 2 of the 0H groups are replaced by -COR5 groups where R5 represents hydrogen, alkyl or phenylalkyl. The production of intermediates is also described and some of these are novel.</p> |
