Green methodology to synthesis heterocyclic diazo dyes using superacid Aquivion® PFSA PW98 as an efficient catalyst
A heterocyclic diazo dye containing the coumarin structure, specifically 7-hydroxy-4-methyl-8-(4-nitrophenyl azo)-6-(4-nitrophenyl azo) coumarin, was prepared using Aquivion PFSA resin. This resin has been shown to be an interesting, effective, and selective acidic catalyst in the diazotization reac...
