Stereoselective Photodimerization of 3‑Arylindenones in Solution and in the Solid State
dataset

of 3-arylindenones in solution and in the solid
state was examined. Irradiation of 3-arylindenones in benzene exclusively
gave C2-symmetric anti-HH cyclobutane dimers in good yields. In contrast, photolysis in
the solid state afforded syn-HH cyclobutane dimers
efficiently, which was considerably influenced by the molecular arrangement
in the crystal lattice.
