Chemistry comprehensive experiment is in the basic core position in university chemistry teaching. Combined with the our latest research results, we designed a visible light-induced synthesis of selenium-containing seven-membered medium-sized N-heterocycles comprehensive experiment. Through substrate design and preparation→visible light catalysis synthesis→structure characterisation and analysis, students are systematically trained in skills such as continuous multi-step synthetic operation, process analysis and structure analysis, so as to cultivate the systematic and comprehensive nature of students' learning. On this basis, students can fully understand the frontiers and advantages of photochemical reactions and cultivate their awareness of green chemistry.
