Article abstract of DOI:10.1246/cl.1992.2051

The photochemical reactions of 9-benzyloxytriptycenes in methanol were found to give 2-(9-fluorenyl)benzaldehyde acetals and benzyl 2-(9-fluorenyl)phenyl ketones.Intermediacy of norcaradienes and two kinds of singlet carbenes has been demonstrated by quantum yields, light intensity dependence, competitive reactions, and substituent effects.
