small ([alpha]D(25) = -23 and +23 degrees). Computational studies suggest that the latter result is due to presence of a minor conformation of 13 possessing a larger rotation of opposite sign than the major conformation. Both 7 and 13 showed strong circulardichroism and moderately strong circularly polarized luminescence. A byproduct of these syntheses was 9,10,19,21-tetraphenyldiphenanthro[9,10-b:9

7-Oxonorborn-2-ene-5,6-dicarboxylic anhydrides (I) and cyclohexa-1,3-diene-5,6-dicarboxylic anhydrides (II), with various substituting or fused groups, give substituted benzenes (III) in substitution-dependent yields when irradiated at 2537 Å. A possible rationale for the photolyticdecarbonylation is discussed. Some synthetic and groundstatereactions of the systems studied are also described.
