摘要：

化学综合实验在大学化学教学中处于基础核心地位。作者结合团队最新研究成果，设计了一个可见光诱导合成含硒七元氮杂中环的综合实验。通过底物设计制备→可见光催化合成→结构表征分析等环节，对学生连续多步合成操作、过程分析和结构解析等技能进行系统训练，培养学生学习的系统性、全面性。在此基础上，学生可以充分了解光化学反应的前沿和优势，培养学生绿色化学意识。

Abstract:

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.
