An eco-friendly methodology for the synthesis of azocoumarin dye using cation exchange resins
An azo dye bearing coumarin moieties were prepared by diazotization of 4-Nitro aniline using amberlyst-15 as an acid catalyst then coupling of the obtained diazonium salt with coumarin. The obtained dye were characterized via UV-Vis, FT-IR, and 1H, 13C NMR spectroscopy This eco-friendly procedure se...

| description | An azo dye bearing coumarin moieties were prepared by diazotization of 4-Nitro aniline using amberlyst-15 as an acid catalyst then coupling of the obtained diazonium salt with coumarin. The obtained dye were characterized via UV-Vis, FT-IR, and 1H, 13C NMR spectroscopy This eco-friendly procedure seeks to get ride of the restrictions of the diazotisation traditional method such as using of strong acids, harmful solvents, modest yields and difficult purification, In addition, the pluses of this procedure include moderate conditions with good conversions, avoidance of harmful acids, simple product isolation process, selective, reduce by-products and purification procedures, recyclability of the catalyst and inexpensive procedures. |
