Abstract
In this study, Yb immobilized NaY zeolite catalyst (Yb/NaY) was obtained by a hydrothermal method and characterized by XRD, BET, FT-IR, ICP-AES, and NH3-TPD. The catalyst displayed good catalytic activity when applied to the synthesis of quinoxalines via condensation of α-hydroxyketones with 1,2-diamines, and could be reused several times without any loss of catalytic activity.
Graphical abstractA recyclable and efficient Yb/NaY zeolite catalyst was obtained for catalyzing the condensation synthesis of quinoxaline. The catalyst gave desired products in good to excellent yields (up to 94%), and could be reused several times without any loss of its catalytic activity.Figure optionsDownload full-size imageDownload as PowerPoint slide
