Description
Summary:A green protocol for the synthesis of novel rhodamine derivatives employing a highly efficient and recyclable magnetic Fe3O4@silica sulfuric acid nanocatalyst in greener solvent ethylene glycol is demonstrated. In comparison with the known methods for the synthesis of rhodamines, our method offers several benefits such as mild reaction conditions, short reaction time (5 h) and high yield (up to 79%) of the products. Interestingly, the magnetically separable nanocatalyst was reused at least five times without significant loss in catalytic activity. All the novel derivatives are well characterized by 1H NMR, 13C NMR, and mass spectrometry. A green approach for the synthesis of novel rhodamine derivatives is demonstrated by reacting 3‐(N,N‐disubstituted amino)phenol and 2,3‐diphenyl maleic anhydride by using a highly efficient and recyclable magnetic Fe3O4@silica sulfuric acid nanocatalyst in greener solvent ethylene glycol.
