Abstract
Irradiation of 1,2-diphenylcyclobutene (1) in methanol affords the methyl ethers, 1,2-diphenyl-1-methoxycyclobutane (2a) and 1-(α-methoxybenzyl)-1-phenylcyclopropane (3a). In acetic acid and in a mixture of water and dioxane, the corresponding esters (2b and 3b) and alcohols (2c and 3c) are formed, respectively. Evidence supporting the involvement of a singlet species was obtained upon finding that the fluorescence of 1 is substantially quenched upon the addition of methanol or acetic acid to a solution of 1 in hexane.
