Norbornadiene-quadricyclane reactivity

A detailed study of the photochemical cyclization of norbornadiene to quadricyclane using aryl phosphine copper(I) halides has been reported. The quadricyclane (144) is formed on irradiation of the norbornadiene (145) at 366 nm. The quantum yield (0.68) for the process is high. The influence of triplet sensitizers ( metal complexes, biacetyl and acetophenone) were found to be less efficient ( ct> = 0.1). The authors suggest that the lowest singlet state of norbornadiene is much more reactive than the triplet state. ... [Pg.256]
