Photolysis of benzonorbornene-2,3-dione in acetone at –60 °C yields a diastereomeric mixture of 1-(indanyl)-1H-indenes considered to arise from [8π+ 8π+ 2 σ]-cyclodimerisation of isoindene: these structures have been confirmed by synthesis, and full stereochemical assignments made following conversion into dihydro-derivatives.
Six cyclic stilbene derivatives with hindered free rotation around the C(vinyl)–C(phenyl) single bond were synthesized by McMurry coupling. The torsion angles around the double and the single bond, and the CC bond length were obtained for many of the compounds from their solid-state structures. The photochemical isomerization was subsequently investigated for all derivatives under various conditions
