Abstract

U cilju proučavanja fotokemijskog ponašanja derivata o-divinilbenzena sintetizirana su tri početna supstrata. Disupstituirani furanski derivati o-divinilbenzena 1-3 pripravljeni su Wittigovom reakcijom u obliku smjese cis,cis-, cis,trans- i trans,trans-izomera. Smjese izomera početnih spojeva podvrgnute su fotokemijskim rekcijama ciklizacije u neutralnom mediju uz dodatak joda. Njihova fotokemijska reaktivnost i reakcijski mehanizam uspoređeni su s fotokemijskim ispitivanjima u kiselim uvjetima.

Abstract (english)

In aim to study photochemical behaviour of o-divinylbenzene derivatives three compounds were synthesized. Disubstituted furan derivatives 1-3 were prepared by Wittig reaction as a mixture of cis,cis-, cis,trans- and trans,trans-isomers and were subjected to photochemical cyclization reactions in neutral medium in the presence of iodine. Studied photochemical reactivity and previously investigated photochemistry in acidic medium were compared.
