Abstract

Described is an organic synthesis experiment that demonstrates the electronic transmission by substituents. The effect of substitution at the para-position of the styryl ring of 1,3-diphenyl-2-propenones (chalcones) by typical electron-donating or -accepting groups can be observed by proton and carbon-13 NMR spectroscopy.

  Abstract:
  The solvent-free synthesis of 20 chalcones was carried out by grinding the benzaldehyde (unsubstituted, 4-methyl, 4-methoxy, 3-chloro, or 4-chloro) and the acetophenone (unsubstituted, 4-methyl, 4-bromo, or 4-methoxy) in the presence of solid sodium ...
