Oxidation of bisnaphthols (1a-c) with DDQ resulted in the formation of 10a-a″, 10b-b″, 14a-c and 19a-c in addition to earlier reported products. Structures were assigned on the basis of detailed spectral analyses(1H, 13C, 1H1H HOMOCOSY and FUCOUP). Structures 10b, and 14c and 19a were further confirmed by single crystal X-ray analyses. The formation of these compounds has been explained by a suitable

Irradiation of the title compound (2) gave a wide range of products, identified as compounds (3)–(7) on the basis of spectroscopic data and chemical evidence, which result from β-cleavages and intramolecular cycloaddition.
