Process for production of sulfonium compounds.

摘要

Process for production of sulfonium compounds represented by the general formula (III), comprising reacting p-dialkylsulfoniophenols represented by the general formula (I) and carbonyl halogenide compounds represented by the general formula (II) in the presence of secondary amine having the structure in which two secondary alkyl groups are linked to the nitrogen atom. General Formula (I): <CHEM> General Formula (II): <CHEM> General Formula (III): <CHEM> (all the symbols are as described in the appended claims). e
