Document Type and Number:
WIPO Patent Application WO/2011/010524
Kind Code:
A1
Abstract:
Provided is a process by which high-purity alkoxybenzenesulfonyl chlorides can be produced industrially, easily and efficiently. A process for the production of alkoxybenzenesulfonyl chlorides represented by general formula (2) [wherein R1s may be the same or different and are each a C1-4 lower alkyl group, or the R1s of two OR1s which are adjacent to each other may be united to form a ring; and n is an integer of 2 to 5], characterized by subjecting the reaction product of sulfuryl chloride and N,N-dimethyl- formamide to a reaction with an alkoxybenzene represented by general formula (1) [wherein R1s may be the same or different and are each a C1-4 lower alkyl group, or the R1s of two OR1s which are adjacent to each other may be united to form a ring; and n is an integer of 2 to 5].
