METHOD FOR PRODUCING TRISPHENOLS AND MONOESTER DERIVATIVES THEREOF, AND 4-ACYLARALKYLPHENOL DERIVATIVES

WIPO Patent Application WO/2010/134559

A1

Provided are a method for industrially easily producing trisphenols, which are useful as starting materials for polymer compounds such as epoxy resins and polycarbonate resins and starting materials or additives for photoresists, at a high purity and high yield, and 4-acylaralkylphenol derivatives. Specifically, provided are: a method for producing a trisphenol represented by general formula (1) [wherein R1 to R4 independently represent a hydrogen atom, an alkyl group, an alkoxyl group, an aromatic hydrocarbon group, a halogen atom, an acyloxy group or a hydroxyl group; R5 and R6 independently represent a hydrogen atom or an alkyl group; R7 represents a hydrogen atom or an alkyl group; R0 represents an alkyl group, an alkoxyl group or a halogen atom; n represents 0 or an integer of 1 to 4, provided that in the case where n is 2 or greater, R0's may be either the same or different; and R9 to R11 independently represent a hydrogen atom, an alkyl group, an alkoxyl group, an aromatic hydrocarbon group, a halogen atom or a hydroxyl group], which comprises using, as a starting material, a 4-aralkylphenol derivative represented by general formula (2) [wherein R1 to R4, R5 and R6, R0 and n are each as defined in general formula (1); and X represents a hydrogen atom or a leaving group which can be substituted by a hydrogen atom, provided that in the case where n is 1 or greater, R0 does not attach to the 4-position of the phenyl group]; and a 4-acylaralkylphenol derivative.
