Irradiation of 6,7-benzobicyclo[3.2.0]hepta-3,6-dien-2-one (2) in a rigid glass at −196 °C leads to the formation of 3,4-benzotropone (1), which exhibits a characteristic UV−vis absorption extending to 535 nm and dimerizes to give syn- and anti-[π8 + π10] dimers 7 and 8 upon thawing the glass. The rate constant of the thermal dimerization of 1 is 12 ± 3 M-1 s-1 at −78 °C. Photochemically, 1 is stable

The IR spectra of 3,4-benzotropone (2) and naphtho[2,3-c]tropone (3) isolated in nitrogen matrices at 13 K were directly observed. These tropones were generated in the matrices by the photoisomerization of 6,7-benzobicyclo[3.2.0]hepta-3,6-dien-2-one (4) and naphtha[2,3-f]bicyclo[3.2.0]hepta-3,6-dien-2-one (5), respectively. The observed IR bands of the photoproducts were in good agreement with the
