Abstract: Sensitized photoaddition of coumarin to 9,10-dicyanoanthracene via electron transfer was reported. A dramatic enhancement of the rate of the photoaddition reaction was observed in the presence of biphenyl (BP). The possible mechanism was discussed.

Key words: secondary electron transfer, coumarin, biphenyl, 9,10-dicyanoanthracence, photoaddition
