D1) Knowledge and understanding at the end of the class, the student will have a good knowledge of fundamental principles of d-metal organometallic chemistry, of homogeneous catalysis, and of its applications to the main industrial processes and to photocatalysis. In particular, the student will be capable to understand and describe the coordination chemistry of organic molecules to metal centers, and the expected modifications of the physical-chemical properties and of the reactivity for both the organic moiety and the metal. D2) Applying knowledge and understanding: the student will be capable to predict the properties and the reactivity of an organic molecule bonded to a specific metal center. As far as the catalytic processes is concerned, he/she should be able to understand the relationships between the structure of the organometallic catalyst and its catalytic performances. D3) Making judgements: the student should be able to design an organometallic compound by choosing the proper combination between the metal and the ligands in order to have a specific reactivity, in particular, by taking into consideration the main steps of the catalytic cycle where it is involved. D4) Communication skills: at the end of the class the student will manage to master and expose clearly the concepts acquired at point D1, demonstrating to have acquired a good general knowledge and understanding of the topics and the capability of making logical connections between different parts. D5) Learning skills: at the end of the course the student will be capable to get autonomously a deeper knowledge of the topics dealt with in the class, including through the reading and comprehension of textbooks and of articles published on specific scientific journals.

Classroom lessons given by the two Professors of the course by using Power Point presentations. A visiting Professor from a foreign University will be invited to give a number of lessons about a specific topic. Depending on the timeframe, the students will be organized in working groups (or working individually, depending on the number of students) and will be asked to give an oral presentation about a scientific paper, chosen among a number of proposed papers, dealing about a topic of UpToDate research. The latter activity is aimed at achieving Objective D5.
All the Slides shown during lessons are made available to the students through the Moodle platform. Additional material, i.e. scientific publications, is uploaded in the Moodle platform to invite the students to deepen specific topics.
Oral examination (with a final mark given in n/30) consisting in a few questions on both the organometallic and its industrial applications (at least 3 or 4 in total). In answering them, the student is expected to show that he/she has acquired a good general knowledge and understanding of the topics and that he/she can make logical connections between different parts. The evaluation grid adopted is as follows: Excellent (30 - 30 cum laude): excellent knowledge of the topics, excellent language property, excellent analytical ability, ability to brilliantly apply theoretical knowledge to concrete cases. Very good (27 - 29): good knowledge of topics, remarkable language property, good analytical ability, ability to correctly apply theoretical knowledge to concrete cases. Good (24-26): good knowledge of major topics, fair language property, adequate ability to apply theoretical knowledge to concrete cases. Satisfactory (21-23): possession of the fundamental knowledge of the teaching but incomplete mastery of some main topics, satisfactory ownership of language, and sufficient ability to apply theoretical knowledge to concrete cases. Sufficient (18-20): minimal knowledge of the main topics of the teaching and technical language, limited ability to adequately apply theoretical knowledge to concrete cases. Insufficient: lack of acceptable content knowledge of various program topics.
The SDGs relevant to this course are number 9 and 12.
