| Abstract: | Energetics of formation of the intermediate during the photocyclisation of phenylbenzoquinone (PBQ) to 2-hydroxydibenzofuran (HDBF) in methanol solvent has been investigated by employing the time-resolved photoacoustic calorimetric (TRPAC) technique. The study, in conjugation with the nanosecond/microsecond flash photolytic observations, confirms the formation of a long lived intermediate during the photocyclisation reaction. TRPAC result and semi-empirical (AM1 and PM3) calculations suggest that the intermediate is a biradical. |
