Document Type and Number:
WIPO Patent Application WO/2002/048101
Kind Code:
A1
Abstract:
A process for directly producing the target sulfonium salt not via a metathesis step without using a large excess of an acid. The process comprises reacting an aryl compound (A) in which at least one of the carbon atoms of the aryl group has a hydrogen atom bonded thereto with a sulfoxide compound (B) represented by the formula R?1¿SOR?2¿ (wherein R?1¿ and R?2¿ may be the same or different and each represents an optionally substituted hydrocarbon or heterocyclic group) in the presence of a strong acid (C) represented by the formula HMX¿m?Y¿n? (wherein M represents a Group IIIa or Va element of the Periodic Table; X represents halogeno; Y represents hydroxy; and m and n are integers satisfying the relationships m + n=4 and 0 ≤ n ≤ 3 when M is a Group IIIa element or satisfying the relationships m+n=6 and 0 ≤ n ≤ 2 when M is a Group Va element).
