Learning Outcomes
Provide students with instruments to critically tackle complex molecules and reaction mechanisms.
Introduction to the main laboratory techniques in order to prepare the student to be autonomous in an organic synthesis laboratory so that he can face and solve the problems he will face in total safety
Prerequisites
Spectroscopic Methods in Organic Chemistry: Knowledge of the most important spectroscopic techniques (mainly IR and NMR) for the determination and characterization of organic molecules. The elaboration of the obtained data allows to intervene in the synthesis and analysis of the organic substances considered.
Teaching Methods
Lectures for the advanced organic chemistry module. For the PESF module The course consists of three parts.
The first part concerns a series of lectures focused on safety and on the main synthesis techniques in an organic synthesis laboratory. At the end of this part, students are provided with reaction procedures from scientific articles, which are translated and analyzed on the blackboard.
The second part consists of the laboratory, where the students will practice a series of reactions.
The third part of lectures concerns the search for information in scientific literature, some unconventional synthesis techniques and industrial synthesis. One of these lessons is held in the computer room where students have the opportunity to search for information in the scientific literature through the use of databases, search engines and sci-finders.
The frontal lessons are held with the support of power point slides that are provided to students at the beginning of the course.
Optional seminars held by external speakers are also offered every year.
Additional Information
Supporting material to the course will be added to the DIR platform
Assessment Methods
For the advanced organic chemistry module Written test with oral presentation on a topic chosen by the student.
For the PESF module Access to the laboratory is preceded by a first test with 28 questions. 22 questions concern the topics covered in the preparatory lessons for the laboratory. In fact, the student must demonstrate knowledge of the prerequisites for working in safety, as well as the basic techniques that he will use in the laboratory. 6 questions instead concern the resolution of exercises and questions relating to a synthetic procedure in English taken from the scientific literature. In order to achieve the sufficiency, the student must answer at least 16 questions correctly. During the course of the laboratory, the student is evaluated during the various experiments based on the commitment and the results obtained.
A second test of 5 questions concerns the topics covered after the laboratory, such as the search for information in scientific literature, unconventional synthesis techniques and synthesis in industry. To achieve sufficiency, the student must answer at least 3 out of 5 questions correctly.
The final grade will take into account both the written tests and the activity carried out in the laboratory.
