| Abstract: | A series of 6,7-Benzobicyclo[3.2.1]octadienes (10–13) have been prepared. Direct and sensitized irradiation of the dienes gave di-π-methane rearrangement products (14–17). Quantum yields for the direct and sensitized rearrangements were recorded and compared. Substituent effect and structure-multiplicity relationships are discussed. |
