CELLULOSE SULFURIC ACID AS A NEW, BIODEGRADABLE AND ENVIRONMENTALLY FRIENDLY BIO-POLYMER FOR SYNTHESIS OF 4,4'-(ARYLMETHYLENE)BIS(3-METHYL-1-PHENYL-1H-PYRAZOL-5-OLS)

The one-pot multicomponent synthesis of 4,4'-arylmethylene-bis(3-methyl-1-phenyl-1H-pyrazol-5-ol) was performed effectively by tandem Knoevenagel-Michael reaction of aryl aldehydes and 5-methyl-2-phenyl-2,4-dihydro-3H-pyrazol-3-one in the presence of a catalytic amount of cellulose sulfuric aci...
