Silica@PMA Core-Shell Structure as Recyclable Catalyst for the Synthesis of Quinolines

摘要

2-Amino aryl ketones react with aliphatic ketones in 1,2-dichloroethane at room temperature in the presence of a catalytic amount of a PMA-Silica catalyst to afford the corresponding quinolines in high yields. The supported catalyst exhibited excellent activity and stability and it could be reused for at least six times without any loss of activity.
