Regioselective Photocyclodimerization of Cyclohexenones Intercalated on Clay Layers

Article abstract of DOI:10.1246/cl.1992.1405

UV light irradiation of 2-cyclohexenones (1) in the presence of saponite clay resulted in a regioselective photodimerization affording anti-head-to-head dimer.The directed intercalation of 1 was suggested by the regioselective dimerization, X-ray diffraction, IR and photoluminescence analyses.
