Learning outcomes

The purpose of the course is to provide advanced knowledge on the synthesis, the characterization and the chemistry of organometallic compounds with particular emphasis for those of the transition metal elements. The importance of organometallics in homogeneous catalysis will be stressed in order to give instruments for understanding the role of the metal in the key steps of the catalytic reactions. in synthesis and industrial productions. Furthermore the student acquires competences in the use of organometallic and coordination compounds as new molecular functional materials. History and Evolution of Industrial processes correlated to Economics and Sostenibility (12 Green laws).

Prerequisites: Inorganic chemistry knowledge , in particular:

- VSEPR theory for drawing the ligand structure and Symmetry elements and point group designation in metal complexes

-periodic table d electron counting for designing the group to which transition metal is belonging and the relative oxidation state

1.Metal-carbonyls mono and polynuclear. Principal reaction types of coordinated carbon monoxide.

2. Metal-alkyl and metal-aryl compounds. Reactions of carbon-carbon bond formation.

3. Metal-hydrides and dihydrogen complexes.

4. The coordination of olefins to transition metals and the role of the metal to olefin bond in catalytic processes. Dimerization and polymerization - Ziegler-Natta catalysts - stereospecific synthesis of polymers.

5. Metal-carbenes: Fischer and Schrock type. The alkene metathesis and cyclopropanation. Grubbs catalysts.

6. Metal-carbynes. The cyclooligomerization reactions.

7. Reactivity of organic molecules p-coordinated to transition metals. Metal-allyl and -cyclopentadienyl compounds s and p- coordinated.

8. The organometallics catalysis in the synthesis and the industrial processes.

9. Applications of organometallic and coordination compounds in the field of molecular functional materials.

Teaching methods

Lectures and Exercise and self-solved Problems.

Participations to conferences in topics related to the field.

Assessment methods

Assessment of the learning outcomes is carried out by a written test followed by an oral discussion. The test consists of five open questions, whose answers must be not longer than fifteen lines. The time at students’ disposal is two hours. The test will be passed with a score equal or higher than 18/30. The oral test consists of a power-point presentation of a recent scientific organometallic paper (over the last five years) and relative discussion. The final mark is a combination of the written and oral parts of the exam, in a ratio of 60% and 40%, respectively.
