Opis:: About nine substituted (E)-1-(4-methoxyphenyl)-3-phenylprop-2-en-1-ones have been synthesized by solvent-free method. These enones were analyzed by spectral techniques. The characteristic spectral frequencies were correlated through Hammett equation with Hammett substituent constants, F and R parameters using single and multi-regression analysis method. From the statistical analysis results, the quantitative structure activity relationships have been discussed by means of effects of substituents on the spectral frequencies.

Opis:: Some 2’-hydroxyphenylchalcones have been synthesized under microwave irradiation by Claisen-Schmidt condensation between substituted 2-hydroxyacetophenone and substituted benzaldehydes using catalytic amount of SiO2-H3PO4. These chalcones were established by their physical constants and spectroscopic data published earlier. The UV, IR, 1H NMR and 13C NMR spectral data of these chalcone have correlated with Hammett substituent constants, F and R parameters. All the compounds have been subjected to screened for antimicrobial activity.
