    • One promising approach to this problem was reported by Bouas-Laurent and Lapouyade (ref. 12), who showed that irradiation of a mixture of 9-cyanoanthracene and 9,10-dimethylanthracene at rt affords the cross-dimer in high yields. Unfortunately, the outcome of this reaction is highly sensitive to the conditions employed. In polar sovents or at elevated temperatures, the more thermally stable homodimer of 9-cyanoanthracene is formed as the major product.

    • Although 9,10-dimethylanthracene has been reported to homodimerize, it does so only under much more stringent conditions than were employed in the present study, and at no time did we observe the formation of this photoproduct.

    • Interestingly, while neither 9,10-dimethylanthracene or 9,10-dimethoxyanthracene tend to form homodimers, these two compounds do form the cross-dimer quite readily. Unfortunately, this dimer exhibits relatively poor thermal stability. See: R. Lapouyade, A. Castellan and H. Bouas-Laurent, C. R. Seances Acad. Sci., Ser. C, 1969, 268, 217-219.

    • 2 atmosphere in glass Schlenk tubes. Since anthracene derivatives commonly form endoperoxides when irradiated in the presence of oxygen, all solutions were subjected to three freeze-pump-thaw cycles in order to ensure oxygen was excluded from the reaction mixtures. Photodimerization experiments were carried out in a Rayonet reactor fitted with ten RPR3000A lamps.

    • Photoreversion experiments were carried out by irradiating deoxygenated acetonitrile solutions in quartz cuvettes using a PTI C60 photon-counting spectrofluorimeter as the light source (slit width = 2 nm).
