フエン１，１−ジオキシドであつてよい。Therefore, the present invention is characterized in that 3-bromobenzaldehyde or its acetal is reacted with phenol or its alkali metal salt in the presence of a neutral organic solvent and in the presence of copper atoms or copper ions. Provided is a method for producing phenoxybenzaldehyde or its acetal. The alkali metal salt of phenol is preferably
Sodium or potassium salts are particularly preferred, with the sodium salt exhibiting higher selectivity for 3-phenoxybenzaldehyde. The salt is preferably anhydrous since the presence of water reduces the yield of 3-phenoxybenzaldehyde. Anhydrous salts may be prepared by reacting phenol with an alkali metal hydroxide and removing the resulting water as an azeotrope with toluene or xylene. Alternatively, the phenol may be reacted with an alkali metal alkoxide and the resulting alkanol removed by distillation. Neutral solvents include aromatic hydrocarbons such as toluene or xylene; aromatic heterocyclic nitrogen compounds such as pyridine, 2,
They may be 4,6-trimethylpyridine, quinoline or pyridine-N-oxide; dialkylamides such as dimethylformamide or dimethylacetamide; sulfoxides such as dimethylsulfoxide or tetrahydrothiophene 1,1-dioxide.
