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...
