| Abstract: | Four kinds of α, α′-bis （substituted benzylidene） cycloalkanones were synthesized by cross aldol condensation of aromatic aldehydes with cyclohexanone ketal, and token through hydrogen-nuclear magnetic resonance spectra. The influence of ortho-effect on chemical shift of proton was concluded and found ortho- effect was synthetic action of electronic effect and three-dimensional effect. |
| Keywords: | ortho-effect chemical shift hydrogen-nuclear magnetic resonance electronic effect three-dimensional effect |
