Abstract

V magistrski nalogi smo se osredotočili na fotoinducirane (svetloba z valovno dolžino 365 nm) pretvorbe bor difluoro-diketonatnih derivatov. Naš cilj je bil raziskati reakcijsko pot in obseg pretvorb. Osredotočili smo se na fotoinducirane reakcije bor-difluoridnih diketonatnih kompleksov z raznovrstnimi olefini. V začetku smo sintetizirali začetne komplekse iz ustreznih 1,3-diketonov, tako da smo različne 1,3-diketone reagirali z borovim trifluorid eteratom. Nato smo se lotili izvedbe fotokemijskih De Mayo reakcij. Predhodno sintetizirane komplekse smo reagirali z vrsto olefinov, kar je, kot predvideno v literaturi, vodilo do [2+2]-cikloadicij in retro-aldolnih reakcij pri čemer so nastali ustrezni 1,5-diketoni. Na modelnem substratu smo optimizirali reakcijske pogoje in jih uporabili pri pretvorbah na ostalih substratih, kar je vodilo do nastanka želenih produktov.

Secondary title:	Photoinduced transformations of some eninone derivates
Secondary abstract:	The master thesis describes photoinduced (light with a wavelength of 365 nm) transformations of boron difluoride-diketonate derivatives. Our goal was to study the scope of transformations and the reaction pathway. We focused on photoinduced reactions of boron difluoride diketonato complexes with a variety of olefins. First, we synthesized the starting complexes from 1,3-diketones. A variety of 1,3-diketones were successfully reacted as starting compounds with boron trifluoride etherate to give the corresponding 1,3-diketonato complexes. Next, we set out to perform De Mayo-type photochemical reactions. The previously synthesized complexes were reacted with a series of olefins, which, as predicted in the literature, should lead to [2+2]-cycloadditions, followed by retro-aldol reactions to furnish 1,5-diketones. We successfully optimized the reaction conditions on the model substrate and applied them to the transformations of the other substrates, which led to the formation of the desired products.
