2-propen-1-ones
Opis:: A series of titled chalcones were synthesized by aldol condensation between 2-naphthaldehyde and various substituted acetophenones using solid acidic solid sulphated titania catalyst under microwave irradiation. The yields of these chalcones are more than 90 %. The synthesized chalcones are characterized by their physical constants, analytical and spectroscopic data.

Opis:: In this investigation, the authors predicted the effects of substituents on the functional groups of the titled chalcones using Linear Free Energy Relationship through Hammett equation with its constants and Swain-Lupton parameters. The LFER model statistical analysis was carried out using single and multi-linear regression analysis in MS Office 365 XL package. From the LFER analysis outcome, the influence of substituents on the spectroscopic functionality were discussed with their electronic effects such as, polar, inductive, resonance, field and conjugation. The titled compounds were prepared by solvent-free Aldol-Condensation method. The prepared compounds were characterised by their physical constants, micro analysis and spectroscopic data (FT-IR, NMR and Mass).
