Abstract
Pyrogallol, and analogues thereof having an alkyl, carboxy or alkoxycarbonyl substituent in the benzene ring, and their salts, are prepared by oxidizing, preferably by hydrogen peroxide, the corresponding compounds in which 1 or 2 of the OH groups are replaced by --COR.sup.5 groups where R.sup.5 represents hydrogen, alkyl or phenylalkyl. The production of intermediates is also described and some of these are novel.
