Abstract (EN)
In this thesis, a set of Ir–NHC complexes (C1-6) were synthesized starting from imidazolium salts (L1-6), via transmetalation from the Ag–NHC intermediates formed in situ. These [IrCl(COD)(NHC)] type complexes were characterized by using NMR, HRMS and elemental analysis. Then the catalytic activities of selected iridium catalysts having an NHC ligand in the dehydrogenative quinoline synthesis in the presence of low amount of catalyst and strong base were investigated. As a result, this catalytic system resulted with the highest TONs (up to 9.500) for the reaction 2-aminobenzyl alcohol with ketones to give substituted quinolines for ten different examples. General method, illustrated below, used for synthesis of iridium complexes: General method, illustrated below, used for quinoline synthesis:
