B5007 - CHIMICA METALLORGANICA E CATALISI OMOGENEA

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).

Course contents

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.

10. Introduction of spectroscopic characterization UV, IR, NMR features of some transition metal complexes with aid of a free tutorial (University of Ottawa )

Teaching methods

Lectures with Exercise and self-solved Problems.

Participations to lectures in topics related to the field.

blended teaching which induces peer to peer discussion and self study in class during the lesson comprehension

The acquisition of the novel informations and the new methods can be acquired with the criticism driven by good judgment more than superficial added knowledge mainly assumed through memory storage

Assessment methods

Assessment of the learning outcomes is carried out by two distinct presentations two power-point presentations one concerning a recent scientific organometallic paper (over the last five years) and relative discussion. The second succinct presentation will be regard one of the topic treated in the class with some questions to trigger he relative oral discussion.  

Teaching tools
