New pyrazolone derivatives synthesis: comparison of the catalytic effect of three typically different Brønsted acid catalysts on the reaction progression
Volume 7, Issue 1, pp. 1-89, Serial No. 22 , January 2019, , Pages 52-62
Abstract
Via the one-pot condensation reaction of ethyl acetoacetate, aromatic aldehydes, 2,4-dinitrophenylhydrazine, and β-naphthol; new pyrazolone derivatives were synthesized in the presence of three Brønsted acid catalysts. These Brønsted acid catalysts are Silica sulfuric acid (SSA), tetra-n-butyl ... Read More)
