20.500.12556/RUL-145366 Fotoinducirane pretvorbe nekaterih eninonskih derivatov Photoinduced transformations of some eninone derivates 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. 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. fotokemija fluorescenca bor difluoro diketonski kompleks De Mayo reakcija photochemistry fluorescence boron difluoride diketone complex De Mayo type reaction true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2023-04-19 11:00:00 2023-04-19 11:00:04 2023-04-21 09:47:59 0000-00-00 00:00:00 2023 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 21993 149963523 Voncina_Ursa_-_Fotoinducirane_pretvorbe_nekaterih_eninonskih_derivatov.pdf Voncina_Ursa_-_Fotoinducirane_pretvorbe_nekaterih_eninonskih_derivatov.pdf 1 9B4ECCA9802238D4F13FFFDA2C9E4762 fa8dcbaf794be4b9c72f90f4be2a511a7f0330b7285ffce28368eae3a226374d 685fa4b1-de90-11ed-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=168242 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
