Process for preparing 3-phenoxybenzaldehydes and their acetals

摘要

3-Phenoxybenzaldehyde acetals can be prepared by reacting a 3-bromobenzaldehyde acetal with an alkali metal phenolate at a temperature of 130-165 DEG C. In the presence of a copper catalyst and a phenol as the sole solvent. The product acetals can be converted to the corresponding 3-phenoxybenzaldehydes by hydrolysis.
