Abstract
1-benzyl-4-aza-1-azoniabicyclo[2.2.2]octane tribromide was prepared by oxidation of KBr by KBrO3 in sulfuric acid solution. This reagent was found to be an efficient and mild reagent for the thioacetalization of aldehydes using 1,2-ethanedithiole under solvent-free conditions at room temperature. The protection of ketones was achieved under reflux conditions in ethyl acetate as solvent.
