Objectives Advanced concepts of structure and reactivity in Inorganic Chemistry.
Subject 1 h: Introduction to Organometallic Chemistry: Definition; organometallic compounds vs. coordination compounds; history and important representatives.

2 h: Comparison organometallic chemistry of main group and transition metals; nature of M-C bonds; kinetic stability / reactivity of organometallic compounds; beta-elimination; electronegativity and reactivity; stability of main group organyls; routes to main group organyls.

3 h: Handling of air sensitive organometallic compounds: Schlenk technique, glove box; Characterisation of (organometallic) compounds: (heteronuclear) NMR, single X-ray diffraction, mass spectrometry.

4 h: Lithium organyls: synthesis, structure, reactivity.

5 h: Heavier homologues of lithium organyls: Na, K; 2nd group organyls: Be, Mg (Grignard!); 12th group organyls: Zn, Cd, Hg.

6 h: Boranes, Wade-Mingos-Rules; heteroboranes (structure, reactivity, acidity); Zintl-Phases; Zintl-Clusters.

7 h: Coordination Chemistry: transition metal ions (configuration, oxidation states, ionisation, radii); ligands; isomerism; ligand-field theory (d-orbital splitting of different geometries); Tanabe-Sugano diagram; spectro-chemical series; MO-theory and 18 electron rule; electron counting.

8 h: Ligands: actor, spectators, non-innocent; CO as ligand; carbonyl-complexes (bonding and structures); pi-bonded ligands (ethylene, ferrocene); metal-metal bonds (single, double, triple, quadruple, quintuple, sextuple).

9 h: fundamental reactions of transition metal complexes: association-dissociation, oxidative addition – reductive elimination, insertion – deinsertion; ligand exchange; electron transfer; phosphanes as ligands: basicity, Tolman’s angle, chirality.

10 + 11 h Catalysis: Fundamentals, history, comparison heterogeneous vs. homogeneous, economics, TON, TOF, selectivity; Examples: olefin hydrogenation/isomerizatoin, Wilkinson’s hydrogenation catalyst, olefin hydroformylation, Monsanto process, Wacker process.

Carbenes: synthesis, structure, properties and reactivity: Fischer vs. Schrock carbenes; olefin metathesis (Schrock, Grubbs); Wanzlick equilibrium and Arduengo carbenes (N-heterocyclic carbenes); examples for palladium catalysed coupling reactions.
