Abstract
PURPOSE: To prepare the title compound useful as a raw material of pharmaceuticalss, pesticides, dyes, etc., in one step and in high yield, by reacting a 2-carboxyhydroxymethylphenol derivative with an N-containing compound and oxygen, in a basic aqueous medium, in the presence of a metal catalyst.
CONSTITUTION: The objective compound of formula II (X is alkyl, alkoxy, halogen; n is 0, 1), e.g. 2-cyanophenol, is prepared by reacting 1 mole of a 2-carboxyhydroxymethylphenol derivative of formula I with an N-containing compound selected from ammonia, urea and an inorganic ammonium salt, in the presence of 0.05W0.5 g atom of a metal catalyst (e.g. copper metal, copper oxide), in an aqueous medium containing 2W5 moles of a base such as NaOH. The aqueous solution may be a buffer solution containing sodium carbonate and sodium hydrogen carbonate.
