[Summary of the course] In this lecture, organic synthesis and organometallics will be taught through chemical experiments. By carrying out experiments of two topics, "Asymmetric synthesis of chiral molecules via stereoselective carbon-carbon bond formation" and Homogeneous catalysis using transition metal complexes", reaction procedures under inert atmosphere and dry conditions, separation and purification techniques using column chromatography, instrumental analyses such as characterization by NMR and IR spectroscopies and determination of optical purities using HPLC will be taught.
[Aim of the course] This lecture facilitates students' understanding about previous lectures such as Organic Chemistry, Inorganic Chemistry and Chemistry of Catalytic Processes through experiments. Furthermore, students master techniques for synthetic chemical research, and this lecture also facilitates problem-identifying ability and problem-solving ability by communizing results obtained under different experimental conditions and deep discussion. Students will be able to fill a gap between the forefront of chemical research and experimental class through experiments in this lecture.
By the end of this course, students acquire the following ability:
1) Ability to carry out experiment for organic synthetic reactions under inert atmosphere and dry conditions.
2) Ability to carry out experiment for asymmetric synthesis of chiral molecules.
3) Ability to explain mechanisms of homogeneous catalyses based on the combination of fundamental processes of organometallic complexes.
4) Ability to determine molecular structures of organic and organometallic compounds using spectroscopic analyses including NMR.
