Abstract
4-Substituted N -(4-ethynylbenzylidene)anilines (4-HC≡C-C 6 H 4 -CH=N-C 6 H 4 -4-R; R = Me, t -Bu, OMe, F, Cl, Br, I, CF 3 and NO 2 ) 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- N -(4-substituted benzylidene)anilines (4-HC≡C-C 6 H 4 -N=CH-C 6 H 4 -4-R; R = H, Me, t -Bu, F, Br, NO 2 , CN, NMe 2 ). The influence of substituent R on spectroscopic characteristics is discussed.
