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:: A series of N-(substituted phenyl) formamides were synthesised by sulphated titania (TiO2-SO4 2-) catalyzed formylation of substituted anilines and formic acid in acetonitrile medium at room temperature. The synthesised formamide derivatives are characterized by their spectral data. The infrared νNH, CO (cm-1) stretches, chemical shifts(δ, ppm) of NH, COH and ipso carbons(Ar-C-NH) were assigned and correlated with Hammett substituent constants using single and multi-regression analysis. From the results of statistical analyses, the effect of substituents on the spectral data have been studied.
