Lesson 1: group theory, with particular reference to the molecular symmetry, the reducible and irreducible representations and character tables.
Lesson 2: Application of group theory to the IR and Raman spectroscopy and interpretation of infrared spectra.
Lesson 3: Basic principles of nuclear magnetic resonance spectroscopy.
Definition of chemically and magnetically equivalent nuclei (spin system) and notes on the chemical shifts and coupling constants. Particular attention will also be devoted to the interpretation of monodimentional NMR spectra (31P, 19F, 11B, 1H e 13C) of simple molecular compounds containing transition metals.
Lesson 4: UV-Vis, electronic structure and spectra of ions of transition metals.
Lesson 5: Explanation of experience that will be carried out in the laboratory.
Laboratory
The laboratory exercises will focus on the synthesis, characterization and reactivity of inorganic compounds.
1. Synthesis and Spectral and Thermal Properties of Pyrazine-Bridged Coordination Polymers of Copper(II) Nitrate
2. Preparation and NMR Analysis of mer and fac Isomers of Tris(1,1,1-trifluoro-2,4-pentanedionato)cobalt(III).
3. Synthesis of [RuCl2(dppb)(PPh3)] and Identification of the cis- and trans-[RuCl2(dppb)(phen)] Geometrical Isomers via 31P{1H} NMR Spectroscopy
4. Synthesis and Spectral and Thermal Properties of Bis (N, N'-diethyldithiocarbamate) nitrosyl iron(II)
5. Synthesis of Dichlorophosphinenickel(II) Compounds and Their Catalytic Activity in Suzuki Cross-Coupling Reactions.
6. Introduction to Homogenous Catalysis with Ruthenium-Catalyzed Oxidation of Alcohols.
7. Olefins Hydrogenation catalyzed by in-situ generated copper nanoparticles.
Each inorganic compound synthesized will be characterized using the most common techniques for spectroscopic investigation. IR spectra (in solution and in the solid state), UV-Vis spectra and multinuclear NMR spectra (mainly 1H and 31P, 19F, 11B) will be recorded and interpreted. Where possible, for a further characterization of the derivative isolated, will be employed also techniques such as thermogravimetric analysis coupled with differential scanning calorimetry (TGA / DSC) and X-ray fluorescence
