摘要

Photocycloaddition to various aromatic nitriles, occurring across aromatic rings, 2-5 usually proceeds via excited singlet nitriles, and the mechanisms are discussed in relation with exciplexe~.~~~ However, it has been reported that benzonitrile undergoes photocycloaddition to tetrasubstituted, very electron-rich ethylenes at the nitrile function in an excited singlet state, whereas that occurs to less electron-rich olefins across the benzene ...
