Nowadays, the ability to synthesize new bioinspired metal catalysts to improve and broaden the spectrum of catalytic activity is of paramount importance for sustainable chemistry respectful for our environment. This thesis is focused on the design of transition metal complexes (copper and palladium) based on two different classes of organic ligands: benzotriazolyl-phenolates and phosphonates.Different original complexes based on palladium and copper were synthetized from benzotriazolyl-phenolate and phosphonates ligands. The characterization of the new compounds was performed by different physical and physico-chemical methods (electrochemistry, EPR, UV-vis, IR, X-ray crystallography) and quantum chemistry. The generation and characterization of different reduced and oxidized species helped us in the possible mechanisms determination. The obtained compounds were successfully employed as catalysts in different processes as: hydrogen production, alcohol oxidation and DNA cleavage.

This book, which is characterized by many novel interesting and useful features of approach and presentation. The objectives are listed at the beginning of chapter. The contents of each chapter are presented in a clear, accurate and balance view of inorganic chemistry. This book not only fulfils the requirements of the new synthesis but also caters to the students who would like to delve deeper into the subject. It convinces the researchers that there is more to inorganic chemistry than equations!

Transition metals and their complexes have an important impact on chemistry and are found in many application in life in general. Ruthenium and rhodium are two members of noble metals and proved to be suitable for anticancer activity. With the aim of changing the coordination environment in ruthenium and rhodium complexes, this thesis presents a series of Ru(II) polypyridyl and Rh(III) pincer-type complexes. All new Ru(II) and Rh(III) complexes were characterized by NMR spectroscopy, ESI-MS spectrometry and UV-Vis spectrophotometry . For some of the complexes a single crystal X-ray crystallography was performed. The substitution reactions of Ru(II) and Rh(III) complexes with mononucleotides, oligonucleotides and amino acids were studied quantitatively by UV-Vis spectroscopy. Measurements of the activation enthalpies and entropies for all synthesized complexes are supporting an associative mechanism for the substitution process. NMR spectroscopy studies were performed on some Ru(II) complexes where after the hydrolyses of the metal-Cl bond the complexes are capable to interact with guanine derivatives forming monofunctional adducts via N7 atom. The interactions of Ru(II) and Rh(III) complexes with fully complementary 15-mer and 22-mer duplexes of DNA and fully complementary 13-mer duplexes of RNA were studied by UV-Vis spectroscopy. The interactions of ruthenium(II) and rhodium(III) complexes with calf thymus and herring testes DNA were examined by absorption using UV-Vis spectroscopy, fluorescence emission spectral studies by ethidium bromide displacement studies and viscosity measurements. ; eng
