ملخص المقالة :
In this study, a novel acidic magnetic dicationic ionic liquid was prepared in three steps to serve as a green catalyst in organic synthesis. The newly synthesized catalyst was characterized UV- VIS, and VSM analysis. Additionally, the decomposition steps acatalyst were investigated by thermal analysis techniques (TGA/DSC). The synthesized acidic magnetic dicationic ion liquid has a magnetization of about 0.3 emu/g, which is less than FeCl emu.g- 1). Moreover, the catalytic activity of this acidic ionic liquid was successfully tested in the straight forward one-pot synthesis reaction between β-naphthol, aldehyde, and acetamide or Benzamide. The pure products were determined by analyzing their physical data (melting points, IR method has several advantages such as easy work yield, and high atom economy. The catalyst can be reused and recovered without losing activity.
