Abstract
V sklopu magistrskega dela sem sintetizirala karbenske ligande, tako N-heterociklične (IMes in IPr) kot ciklično (alkil)(aminskega) (cAAC), ki so bili nato uporabljeni za sintezo različnih koordinacijskih spojin s kovinskimi karbonili. Uporabila sem kovinske karbonile treh različnih tipov, kovinska heksakarbonila (Mo in W), kovinska bromopentakarbonila (Mn in Re) in dvojedrna kovinska (deka)karbonila (Mn in Re). Pri sintezi koordinacijskih spojin sem preizkusila različne reakcijske pogoje. Uspešno sem sintetizirala tri že znane in osem novih koordinacijskih spojin. Poleg tega mi je s fluoriranjem izhodnega karbonila uspelo pripraviti nov manganov fluorokarbonil. Nastanek spojin sem potrdila z NMR spektroskopijo, novonastale spojine pa sem hkrati okarakteriziral z rentgensko strukturno analizo.

Title:Synthesis and reactivity of coordination compounds of metal carbonyls with carbene ligands
Abstract:
As part of my master's thesis, I synthesised carbene ligands, including N-heterocyclic (IMes and IPr) and cyclic (alkyl)(amino) (cAAC) carbenes, which were then used to prepare various coordination compounds with metal carbonyls. I used three types of metal carbonyls: metal hexacarbonyl (Mo and W), metal bromopentacarbonyl (Mn and Re), and binuclear metal (deca)carbonyl (Mn and Re). During the synthesis of the coordination compounds I experimented with different reaction conditions. I successfully synthesized three already known and eight new coordination compounds. I also managed to synthesise a new manganese fluorocarbonyl by fluorinating the corresponding dimanganese decacarbonyl. The formation of all compounds was confirmed by NMR spectroscopy, while all newly synthesised compounds were also characterised by X-ray structural analysis.

Keywords:cAAC carbene, NHC carbene, coordination compound, metal carbonyl
