Abstract: 10 new l-phenyl-3-(3'-indolyl)-5-substituted phenyl-2-pyrazolines were synthesized by the reactions of phenylhydrazine with 1-(3'-indolyl)-3-substituted phenyl-2-propen-l-ones. The structures of pyrazolines have been confirmed by their elementary analysis and spectral analysis. Agood linear relationship between σHand σ,(σm)in 1HNMR or the lg(KR/KH) and σ(σ+) in MS was discussed.
