Abstract

ABSTRACT: 1-Methyl-3-(triethoxysilylpropyl)imidazolium chloroaluminate ionic liquid anchored on a composite of cellulose and aluminum oxide was easily synthesized and tested for its catalytic activity in one-pot Knoevenagel condensation, Michael addition, and cyclodehydration of 5, 5-dimethyl-1, 3-cycloheanedione (dimedone) with aromatic aldehydes. The catalyst was characterized by Fourier transform infrared spectroscopy, thermal gravimetric analysis, scanning electron microscopy, energy-dispersive spectroscopy, elemental analysis, and atomic absorption technique. It is a non-hygroscopic (as a bench top catalyst), reusable, and environmentally compatible heterogeneous catalyst.
