Abstract
U cilju nastavka proučavanja utjecaja heterocikličke jezgre na fotokemijsko ponašanje konjugiranih butadienskih sustava razvijena je sinteza novih butadienskih derivata s tiofenskom jezgrom. Wittigovom reakcijom sintetizirani su novi derivati, 3-[4-(2-vinilfenil)buta-1,3-dienil]tiofen (1) i 2-[4-(2-vinilfenil)buta-1,3-dienil]tiofen (2) kao smjese cis,trans- i trans,trans-izomera. Za njihovu sintezu trebalo je pripraviti 3-(tiofen-2/3-il)akrilaldehide (3, 4) koji su sintetizirani na dva načina (Wittigova reakcija i reakcija kondenzacije) radi povećanja iskorištenja na produktima, u oba slučaja dobiveni su samo trans-izomeri akrilaldehida. Spojevi 1-4 okarakterizirani su modernim spektroskopskim metodama (jednodimenzionalni i dvodimenzionalni NMR, UV, IR).
Abstract (english)
In the purpose of further studying of impact of the heterocyclic rings on photochemical behavior of conjugated butadiene systems, synthesis of new butadiene derivatives with the thiophene nucleus is developed. New derivatives, 3-[4-(2-vinylphenyl)buta-1,3-dienyl]thiophene (1) and 2-[4-(2-vinylphenyl)buta-1,3-dienyl]thiophene (2), gained as a mixture of cis,trans- and trans,trans-isomers are synthesized with the Wittig reaction. For their synthesis we need to prepare 3-(thiophene-2/3-yl)acrylaldehydes (3, 4). To increase the yield of the product these acrylaldehydes were synthesized in two ways (the Wittig reaction and condensation reaction). Only trans-isomers of acryladehydes were obtained in each case. Compounds 1-4 were characterized by modern spectroscopic methods (one-dimensional and two-dimensional NMR, UV, IR).
