| Abstract: | Photosensitized ionic radical addition of bicyclo[2.2.1]-2,5-heptadiene with CHCl3 and CCl4 was investigated by using aromatic amines as the sensitizers. The reaction has very good regioselectivity. Only 3,5-addn. products such as I and II were obtained for CCl2 addition; with CHCl3, III was obtained. A mechanism involving ionic radical complex intermediate was proposed. |
