solvent-free synthesis - 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
