Development of Pyrene-based Scandium Lewis Acid Catalysts

摘要

Lewis acid-surfactant-combined catalysts (LASCs), including scandium dodecyl sulfate (Sc(DS)3), are highly efficient catalysts that work in water, and our group reported that Sc(DS)3 could catalyze various chemical transformations in water.1),2) Here, we present the development of a new scandium Lewis acid catalyst based on the pyrene structure. As shown below, scandium 1-pyrenesulfonate (Sc(PS)3) was synthesized by the reaction of 1-pyrenesulfonic acid with scandium oxide in water under reflux conditions.
