PROCESS FOR PRODUCTION OF 2-HYDROXYARYL ALDEHYDE COMPOUND

摘要

Disclosed is a process for producing a 2-hydroxyaryl aldehyde compound. Specifically disclosed is a process for producing a 2-hydroxyaryl aldehyde compound, which is characterized by comprising reacting a hydroxyaryl compound with paraformaldehyde in the presence of magnesium chloride and an amine compound represented by formula (a) [wherein R9 represents a C1-3 alkyl group, or two R9's on the same nitrogen atom together form =CH-R10; R10 represents a C6-12 aryl group (provided that the alkyl group is unsubstituted or substituted by a halogen atom); and n represents a number of 0 or an integer of 1 to 10].
