Opis:: Benzimidazole derivatives have been synthesized by solid Nanocatalysts Zirconia and Sulfated Zirconia with Green reusablity method. Synthesis of benzimidazole was carried out by conventional as well as microwave method. Synthesis carried out by reacting o-phenylenediamine and few aldehydes in the presence of catalytic amount of Nanoparticles. Particles used were sized in between 53-100 nm. Nanoparticles and synthesized benzimidazole derivatives were characterized by DLS, powder XRD, SEM-EDX andMass, CHNS, FT-IR, NMR analysis respectively.

Opis:: Series of eleven substituted of (E)-3-(3-methylthiophen-2-yl)-1-phenylprop-2-en-1-ones compounds by cross-aldol condensation reaction of 3-methylthiophene-2-carbaldehyde with various substituted acetaldehyde in the occurrence of Fly-Ash: H3PO4 catalyst. The effect of catalytic activity of this fly-ash:H3PO4 nanocatalyst was studied with the obtained yield of products under solvent-free conditions. The synthesized substituted (E)-3-(3-methylthiophen-2-yl)-1-phenylprop-2-en-1-one compounds was characterized by physical constants, UV, FT-IR, 1H & 13C-NMR spectral data. The infrared group frequencies of ʋ(cm-1) of COs-cis & s-trans, CHip and CHop, CH=CHop, >C=C
