visible photosensitizers for energy transfer to alkenes. On this basis, the E→Z photoisomerization reactions of alkenes with various functional groups under blue light irradiation were performed with moderate to high selectivity. The mechanistic studies suggested that the reactions involved energy transfer (EnT) from the photo-excited copper acetylide to the alkene via the singlet excited state.
人们发现乙炔铜配合物可作为可见光敏剂,将能量转移至烯烃。在此基础上,在蓝光照射下进行了具有不同官能团的烯烃的E→Z光异构化反应,具有中等到高选择性。机理研究表明,该反应涉及从光激发乙炔铜通过单重激发态到烯烃的能量转移(EnT)。
