Abstract

Cilj ovog rada bio je prirediti nove heterocikličke stilbenske sustave koji će se podvrgnuti termičkim ispitivanjima u pokušaju sinteze indanskih i indenskih derivata. Početni prekursori pripravljeni su Wittigovom reakcijom, pri čemu su dobiveni stilbenski i monosupstituirani sustavi. Termička ispitivanja u kiselom mediju provedena su na pripravljenim stilbenskim sustavima, a prisutnost indanskih i indenskih produkata uočena je samo kod tiofenskih derivata. Kvantno-kemijskim metodama ispitana su sva eksperimentalna zapažanja dobivena u radu.

Abstract (english)

The aim of this work was to prepare heterocyclic stilbene systems that will be subjected to thermal reaction in an attempt to synthesize indane and indene derivatives. The initial precursors were prepared by the Wittig reaction, whereby stilbene and monosubstituted systems were obtained. Thermal reactions in acidic medium were performed on the prepared stilbene systems, and the presence of indane and indene products was observed only in thiophene derivatives. All the experimental observations obtained in the work were examined by quantum-chemical methods.
