Abstract

4-Substituted <i>N</i>-(4-ethynylbenzylidene)anilines (4-HC≡C-C<sub>6</sub>H<sub>4</sub>-CH=N-C<sub>6</sub>H<sub>4</sub>-4-R; R = Me, <i>t</i>-Bu, OMe, F, Cl, Br, I, CF<sub>3</sub> and NO<sub>2</sub>) have been prepared by condensation of 4-ethynylbenzaldehyde with appropriate anilines under mild conditions in good yields. The products obtained were fully characterized by GC-MS, IR, NMR and UV-VIS spectroscopies and their properties were compared with a series of 4-ethynyl-<i>N</i>-(4-substituted benzylidene)anilines (4-HC≡C-C<sub>6</sub>H<sub>4</sub>-N=CH-C<sub>6</sub>H<sub>4</sub>-4-R; R = H, Me, <i>t</i>-Bu, F, Br, NO<sub>2</sub>, CN, NMe<sub>2</sub>). The influence of substituent R on spectroscopic characteristics is discussed. <p>
