Photochemical transformations in some cyclopropyl ketones

Irradiation of trans-1-benzoyl-2-trans-styrylcyclopropane (IIa) and trans-1-p-toluoyl-2-trans-styrylcyclopropane (IIb), leads to formation of cis disubstituted cyclopropanes (IIIa) and (IIIb) respectively.However, photolysis of trans-1-trans-cinnamoyl-2-phenylcyclopropane (IV) results in isomerzation of the α,β-double bond to produce V.Photolysis of trans-1-trans-p-methoxycinnamoyl-2-p-methoxyphenylcyclopropane (VI), by contrast, produces only a cyclobutane dimer formulated as (VII).Irradiation of 7-phenyl-3-benzylidenespirooctan-2-one (IXb), under identical conditions, leads to isomerisation around the C=C bond.The structural assignments are based, interalia, on 13C NMR and 1H NMR spectral data.
