Abstract:Abstract. Novel series of diversely substituted acetyl pyrazoline having biphenyl carbonitrile motif have been synthesized. The reaction of 2-cyno-4'-bromomethyl biphenyl with1-(4-hydroxyphenyl)-ethanone resulted in acetophenone derivative of biphenyl-2-carbonitrile. This acetophenone derivative was condensed with substituted aromatic aldehyde in mixed solvent resulted in various substituted chalcones. These chalcones were further cyclized using hydrazine hydrate in presence of glacial acetic acid to produce t… Show more
