The photochemistry of newly synthesized 8,9-diphenyltricyclo[5.2.1.0^2,6]deca-4,8-dien-3-one (1) has been explored. A novel [1, 3] sigmatropic rearrangement via a singlet excited state was observed as well as a [2 + 2] intramolecular cycloaddition via a triplet excited state. The formation of an intramolecular singlet exciplex was indicated by emission spectra.
