Trans Isomerization

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.
