Green Synthesis of Polysubstituted Benzenes Using Cellulose Sulfuric Acid

Some 2-amino-2,6-dicyano-3,5-disubstituted benzenes have been synthesized in the aqueousmedia using 1,3-dikeones, malononirile, primary or secondary amines and cellulose sulfuric acid as thebiodegradable catalyst. However the reaction resulted in pyridines in the presence of organic acids suchas N-hydroxybenzamide or p-toluenesulfonic acid.The products have shown fluorescence properties in solid and solution phases. Photophysicalproperties (λAbs., λFlu.) of the synthesized compounds in CH2Cl2, CH3CN and CH3OH have beenmeasured.
