Abstract

Irradiation, through Pyrex, of an acetonitrile-methanol (3: 1) solution of 1, 4-dicyanobenzene (1) and 1, 5-hexadiene (9) leads to formation of ortho and meta cyclic adducts (13-16) arising from the intermediate exciplex. There was no evidence for interaction between the two double bonds of this nonconjugated diene. The oxidation potential of 9 is high enough (> 3 V vs. sce) to preclude single electron transfer (SET); no photo-NOCAS products are ...
