Abstract:
1,2-Diphenylcyclopropane (1) was found to be oxidized on illuminated ZnO in the presence of air while 1-(p-methoxyphenyl)-2-phenylcyclopropane (2) and 1,2-bis(p-methoxyphenyl)cyclopropane (3) were found to be similarly oxidized on illuminated CdS. Compounds 2 and 3 were found, also, to undergo a rapid photochemical cis-trans isomerization on CdS whereas 1 did not undergo such isomerization. An electron transfer mechanism involving formation of the radical cations of the substrates is proposed.

Abstract:
The solution phase photochemistry of benzobarrelene derivatives (8) and (11), containing electron-donating and electron-withdrawing substituents, has been studied. The structures of the photoproducts (16)/(20) and (17)/(21) indicate clearly that vinyl-vinyl nitrile (aldehyde) bridging is not operating. The formation of these products is discussed in terms of the stabilizing effect of the substituents on the radical and the destabilizing effect on the formation of the cyclopropane ring.

Abstract:
The potential energy surfaces of dissociations and isomerizations for butyrophenone and its α-substituted derivative in low-lying electronic states have been studied with use of the CASSCF and DFT methods. A three-surface (S1, T1 and T2) intersection was found in the present work and this plays an important role in the S1 → T1 process for butyrophenone and related aromatic carbonyl compounds. Examination of these results provides some new insights into the mechanistic photochemistry of aromatic ketones. The most probable mechanism leading to formation of a cyclopropane moiety was obtained on t
