20.500.12556/RUL-172596 Koordinacijske spojine karbenov s halogenidi prehodnih elementov raziskava reaktivnosti in struktur Coordination Compounds of Carbenes with Transition Metal Halides Investigation of Reactivity and Structures Namen tega diplomskega dela je bil testirati reaktivnost IPrNHC karbenov s halogenidi prehodnih elementov. V okviru diplomskega dela sem najprej sintetiziral izhodne spojine, torej IPrNHC karben in [IPrNHCH][F] reagent, ki sem ju nato uporabljal pri reakcijah s halogenidi prehodnih elementov. Vse reakcije sem izvajal v inertnem okolju na Schlenkovi liniji v brezvodnih topilih (MeCN, THF ali DFB). Uspešnost reakcij sem ovrednotil z merjenjem NMR spektrov reakcijskih mešanic. Večina reakcij ni dala željenih rezultatov. Med uspešne reakcije lahko štejem reakciji IPrNHC z CrCl$_2$ in ZnCl$_2$ v THF pri sobni temperaturi, reakcija IPrNHC z MoCl$_5$ v THF pri 80 °C ter reakcija [IPrNHCH][F] s CdF$_2$ v MeCN pri 80 °C, pri kateri so nastali produkti IPrNHC-CrCl$_2$-IPrNHC, [ZnCl$_2$(IPrNHC)(THF)] in [IPrNHCH][MoOCl$_4$(THF)]. Produkte teh reakcije sem uspešno kristaliziral, ter jim določil strukturo z rentgensko strukturno analizo. The objective of this thesis was to investigate the reactivity of IPrNHC carbenes with transition-metal halides. Initially, the starting compounds were synthesized, namely the IPrNHC carbene and the [IPrNHCH][F] reagent, which were subsequently employed in reactions with transition-metal halides. All reactions were conducted under an inert atmosphere using a Schlenk line and anhydrous solvents (MeCN, THF, or DFB). The progress and outcomes of the reactions were evaluated by recording and analyzing NMR spectra of the reaction mixtures. The majority of the attempted reactions did not yield the desired products. Nevertheless, several reactions were successful, including the reactions of IPrNHC with CrCl$_2$ and ZnCl$_2$ in THF at room temperature and the reaction of IPrNHC with MoCl$_5$ in THF at 80 °C, and the reaction of [IPrNHCH][F] with CdF$_2$ in MeCN at 80 °C. These reactions afforded IPrNHC-CrCl$_2$-IPrNHC, [ZnCl$_2$(IPrNHC)(THF)], [IPrNHCH][MoOCl$_4$(THF)] and [IPrNHCH][HF$_2$]∙2MeCN. The products were successfully crystallized, and their molecular structures were unambiguously determined by single-crystal X-ray diffraction analysis.
