Nano-TiCl4 /gama-Al2O3: an Efficient Heterogeneous Solid Acid Catalyst for Rapid and Solventless Synthesis of Azo dyes based on 2-Naphthol at Room Temperature

چکیده مقاله

At the beginning of the new century, synthesis of organic compounds using grinding technique under solvent-free conditions has received much attention, as it provides manipulative simplicity, easier workup, and higher yields which match with the green chemistry protocol. On the other side, more attention has been directed toward the application of solid acids in organic synthesis because such reagents not only simplify purification processes but also help prevent release of reaction residues into the environment.
