Indium tribromide-catalyzed chemoselective dithioacetalization of aldehydes in non-aqueous and aqueous media

Indium tribromide efficiently catalyzes the chemoselective dithioacetalization of aldehydes in the presence of ketones in dichloromethane. The catalyst is also active in water, which can be reused, in the same pot, for several times without any decrease in the yield of reaction.
