The introduction of the frontier research in the photocatalysis field is important in the teaching of organic chemistry laboratory. It not only expands students’ knowledge of photochemical, multi-component catalytic cascade and free radical reactions, but also deepen students’ understanding of nucleophilic reaction mechanism and radical and ionic intermediates. The experiment involves three parts: product preparation, mechanism exploration and experimental expansion of imidazoline compounds, including various organic experimental operations such as anhydrous and anaerobic, reaction monitoring, separation, purification and product characterization.
- Visible photoredox catalysis,
- Multi-component reaction,
- Tandem reaction,
- Divergent synthesis
