METHOD FOR PRODUCING CYANOBENZALDEHYDE COMPOUND

摘要

PROBLEM TO BE SOLVED: To provide an industrially advantageous method for producing cyanobenzaldehyde compound. SOLUTION: This method for producing the cyanobenzaldehyde compound represented by general formula (II) (m is an integer of 0-4; and X and Y are each a halogen atom) comprises hydrolyzing dihalogenomethylbenzonitriles represented by general formula (I) (m is an integer of 0-4; X and Y are each a halogen atom) without using a catalyst in the presence of extremely excess amount of water.
