Zirconium Tetrakis(dodecyl Sulfate) [Zr(DS)₄] as an Efficient Lewis Acid–Surfactant Combined Catalyst for the Synthesis of Quinoxaline Derivatives in Aqueous Media

Abstract

Zirconium tetrakis(dodecyl sulfate) [Zr(DS)₄] efficiently catalyzes the synthesis of quinoxaline derivatives via the condensation of 1,2-diamines with 1,2-diketones in H₂O as a green media at room temperature. Using this method, the title compounds are produced in good to excellent yields and relatively short reaction times.
