ORGANOMETALLIC CHEMISTRY OF GOLD, PALLADIUM AND IRIDIUM COMPLEXES BEARING N-HETEROCYCLIC AND/OR ACYCLIC DIAMINO CARBENES

Abstract

This thesis focuses on the organometallic chemistry of gold, palladium, and iridium complexes that bear a N-heterocyclic carbene (NHC) and/or an acyclic diamino carbene (ADC). The first part of this work deals with the syntheses and characterization of several gold NHC complexes that bear a non-classical pyrazole-derived NHC. These complexes have been applied to in vitro cytotoxicity studies. The following chapter reports on the syntheses and characterization of gold complexes that bear a template-synthesized ADC and/or tetrazole-derived NHC. The reactivities of these gold complexes to a Pd(II) dimeric compound, forming Au/Pd hetero-bimetallic complexes, have also been explored. Moreover, the electrochemical and electronic properties of the gold monometallic and Au/Pd hetero-bimetallic complexes have been investigated. Finally, the last part of this thesis discusses the syntheses and characterization of some iridium NHC complexes. The reactivities, as well as electronic and electrochemical properties of the complexes have also been studied.
