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.
在二氯甲烷中有酮存在下,三溴化铟可有效催化醛的化学选择性二硫缩醛化。该催化剂在水中也具有活性,可以在同一罐中重复使用几次,而不会降低反应的产率。
