Abstract
U cilju proučavanja utjecaja heteroatoma i pH vrijednosti na tijek fotokemijske reakcije i formiranja novih policikličkih struktura, proučavan je difuranski derivat o-divinilbenzena 1. Spoj 1 sintetiziran je Wittigovom reakcijom te podvrgnut fotokemijskim reakcijama u kiselom i neutralnom mediju, pri čemu su sintetizirana četiri nova spoja. Kao glavni produkt fotokemijske reakcije u neutralnom mediju dobiven je biciklo[3.2.1]oktadienski derivat 3 intramolekulskom reakcijom cikloadicije. Fotokemijskom reakcijom u kiselom mediju dobiven je dihidronaftalenski derivat 5 kao posljedica protoniranja i 1,6-zatvaranja. Kao posljedica reakcije 10π elektrociklizacije dobiven je fenantrenski derivat 2, u neutralnom i kiselom mediju, koji pri sniženoj pH vrijednosti podliježe sekundarnoj 6π elektrociklizaciji te nastaje pirenski spoj 4. Svi produkti su izolirani i u potpunosti okarakterizirani.
Abstract (english)
In order to study the influence of heteroatom and pH values on photochemical reactions, difurane derivative of o-divinylbenzene 1 was studied. Compound 1 was synthesized by Wittig reaction and irradiated in neutral and acidic medium. Four new compounds were obtained. Bicyclo[3.2.1]octadiene derivative 3 was obtained as main product in neutral medium via intramolecular reaction of cycloaddition. As a result of protonation and 1,6 – closure, dihydronaphthalene derivative 5 was obtained as main product in the acidic medium. As a consequence of 10π electrocyclization reaction, a phenanthrene derivative 2 was obtained in a neutral and acid medium. Secondary 6π electrocyclization of fotoproduct 2 leads to pyrene compound 4, isolated only under reduced pH. All products were isolated and completely characterized by spectroscopic methods.
