Abstract
The nucleophilic reactions of 2,3-dichlorobenzo[b]thiophene 1,1-dioxide with α- and β-glycols, α-diamines, and α-amino alcohols proceed with cleavage of hydrogen chloride to give the previously unknown 3-monosubstituted derivatives of 2-chlorobenzo[b]thiophene 1,1-dioxide. The second functional group (the hydroxyl group in amino alcohols) does not enter into the reaction.
