설명

애플리케이션

1,4-Diazabicyclo[2.2.2]octane bis(sulfur dioxide) (DABSO) is a charge transfer complex that can be used as a sulfur dioxide surrogate:

• In palladium-catalyzed aminosulfonylation process.
• In reaction with aryl bromides to synthesize sodium aryl sulfinates.

It can also be used to activate DMSO and o-vinylanilines for the synthesis of N-aryl-1H-benzo[d]imidazol-1-amine and 4-aryl quinolines, respectively.
