RISFe(HSO4)3'SiO2 as an efficient, heterogeneous and recyclable catalyst for the synthesis of bis-(b-enaminones) and bis-(b-enamino esters)
Year: 2014
Abstract:
Fe(HSO4)3'SiO2 is used to catalyze the condensation of b-diketones and b-keto esters with
aromatic and aliphatic diamines in solvent-free conditions at room temperature. This
afforded the corresponding ...
