Course Objectives

The course aims to provide an in-depth understanding of the synthesis and reactivity of various types of metal-carbon bond. The first part will consist in “synthesis and reactivity” of the most used organometallic compounds of the main-group (with reference only to compounds that have only simple carbon-metal bond) to pass then to study the organometallics of transition (compounds that include both simple bonds and carbon multiple bonds metal). The last part of the course is directed to various methodologies that allow the formation of C-X bonds (X = C, N, O, S, P) using various metals as catalysts of transition and as reactive the various organometallics of main-group studied in the first part of the course.

Course Prerequisites

The student must demonstrate a good knowledge of basic organic chemistry and the chemistry of coordination.

Teaching Methods

The course uses lectures. The duration of the same will be 48 hours, will involve the use of a video projector with which will then projected and discussed slides concerning the different topics of the course, slides also contained, for approach to the subject, in three files in advance provided to the students.

Assessment Methods

The examination includes a final written test of typically 3 h duration. The written test will be organized in the formulation of two questions concerning general topics discussed in the course and of two synthesis exercises related to these topics. The final grade will take into account the accuracy and quality of the responses, the synthetic capacity of the candidate in presenting the required topics
