Using 1,2,4-triphenylbenzene as a photosensitizer, the photoamination of alkenes and alkadienes (1), which had no absorption at > 300 nm proceeded efficiently in the presence of p-dicyanobenzene to give addition products by incorporating both amino andp-cyanophenyl groups. The reaction efficiency was discussed in terms of the relationships between 1 and the photosensitizer in their oxidation potentials and the distribution of positive charge on the reaction site of the cation radical of 1 (1(+.)).
