Facile synthesis of 1-naphthol azo dyes with nano SiO<sub>2</sub>/HIO<sub>4</sub> under solvent-free conditions
Nano-silica supported periodic acid (nano-SPIA) has been utilized as a heterogeneous reagent for a highly efficient and one pot synthesis of azo dyes based on 1-naphthol under solvent-free conditions at room temperature. This method has some advantages, the reaction workup is very easy and the catal...

| description |
Nano-silica supported periodic acid (nano-SPIA) has been utilized as a heterogeneous reagent for a highly efficient and one pot synthesis of azo dyes based on 1-naphthol under solvent-free conditions at room temperature. This method has some advantages, the reaction workup is very easy and the catalyst can be easily separated from the reaction mixture and one-pot procedure. The related products have been obtained in good to excellent yields, high purity and short reaction times. The structures of the products have been characterized by several techniques using UV-Vis, FT-IR, <sup>1</sup>H NMR, <sup>13</sup>C NMR and mass spectra.DOI: http://dx.doi.org/10.4314/bcse.v27i3.13 |
