摘要：

A catalytically active aluminum-based system for Diels-Alder transformations is reported. The system was generated by mixing a -diketiminate-stabilized aluminum bistriflate compound with Na[BAr4Cl] (Ar-Cl=3,5-Cl2C6H3). Solid-state analysis of the catalytic system reveals a unique structure incorporating a two-dimensional coordination polymer. According to the experimental results obtained from several Diels-Alder transformations, the aluminum-based system appears to be a more practical and more robust alternative to the recently reported compounds based on carbon and silicon cations.
