Crystal structure of (2E)-1-(4-ethoxyphenyl)-3-(4-fluorophenyl)prop-2-en-1-one
The title molecule, C17H15FO2, was synthesized by a Claisen–Schmidt condensation with 4-fluorobenzaldehyde and 4′-ethoxyacetophenone. The torsion angles between the 4-fluorophenyl ring and the alkene and the 4′-ethoxyphenyl ring and the 2-propen-1-one ...

La(OH)3 and La2O2CO3 nanorod catalysts for Claisen-Schmidt condensation [PDF]
Abstract La(OH)3 nanorods of 15 nm diameter and up to 700 nm long were synthesized using different pH values of the solution used in the hydrothermal synthesis. A more alkaline solution favored the formation of tiny La(OH)3 nuclei, which grew along the c-axis due to their anisotropic nature and led to the formation of rod-shaped crystals. Calcination
