Abstract
U cilju nastavka proučavanja utjecaja heterocikličke jezgre na fotokemijsko ponašanje konjugiranih butadienskih sustava razvijena je sinteza novih butadienskih derivata s piridinskom jezgrom. Wittigovom reakcijom sintetizirani su novi derivati, 3-[4-(2-vinilfenil)buta-1,3-dienil]piridin (1) i 4-[4-(2-vinilfenil)buta-1,3-dienil]piridin (2) kao smjese cis,trans- i trans,trans-izomera. Za njihovu sintezu trebalo je pripraviti 3-(piridin-3/4-il)akrilaldehide (3, 4) koji su sintetizirani Wittigovom reakcijom, a dobiveni su samo trans-izomeri akrilaldehida s obzirom na stabilnost upotrijebljenog ilida. Spojevi 1-4 okarakterizirani su modernim spektroskopskim metodama (jednodimenzionalni i dvodimenzionalni NMR, UV, IR spektroskopija).
Abstract (english)
As a continuation of the study of heterocyclic core on the photochemical behavior on the conjugated butadiene we developed a synthesis for new butadiene derivatives with pyridine. We utilized Wittig reaction to synthesize new derivatives 3-[4-(2-vinylphenyl)buta-1,3-dienyl]pyridine (1) and 4-[4-(2-vinylphenyl)buta-1,3-dienyl]pyridine (2) as a mixture of cis,trans- and trans,trans-isomers. For the synthesis of the necessary acrylaldehydes (3, 4) we used the Wittig reaction as well, but because of the stability of the ylide this Wittig reaction gave only trans-acrylaldehydes. Compounds 1-4 were isolated and characterized by modern spectroscopic methods (one- and two-dimensional NMR, UV and IR spectroscopy).
