Synthesis of Pincer Lignads and their Complexes with Transition Metals

V magistrski nalogi sem raziskoval sintezo NCN kleščastih ligandov, natančneje sem študiral vpliv metilaminskih in etilaminskih funkcionalnih skupin v ligandih ter študiral razlike med njimi. Po uspešni sintezi in izolaciji ligandov sem sintetiziral NCN kleščaste komplekse s paladijem. Glavna težava pri pripravi kompleksov je bila nestabilnost reagentov in produktov na zraku, zato izolirane spojine niso bile čiste in izkoristki slabi. Kot najbolj primerna reaktanta sta se izkazala butillitij in Pd(SEt2)2Cl2.The master thesis dealt with the synthesis of NCN pincer ligands and further investigated the influence of methyl- and ethylamine functional groups in the ligands and the differences between the two groups. After successful synthesis and isolation of the ligands, I synthesized NCN pincer complexes with palladium. The main problem in preparing the complexes was the instability of the reagents and products in the air, so the isolated compounds were not pure and the yields were poor. Butyllithium and Pd(SEt2)2Cl2 proved to be the most suitable reagents
