AbstractA series of 2-substituted 2,3-dihydroquinazolin-4(1H)-ones were oxidized to quinazolin-4(3H)-ones using tetrabutylammonium peroxydisulfate. The rate and the outcome of the reaction are dependent on the type and nature of 2-substitution. An electron transfer mechanism is proposed for this study, which is supported by the retention or elimination of 2-substitution during the oxidation process.

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.
