Methyl benzoate and other simple arenecarboxylic acid esters have been found to undergo 2+ 2 photochemical cycloaddition at the carbonyl group to furans and certain 1, 3-dienes. These additions afford mixtures of oxetanes and their 2+ 2 cycloreversion products: 4-aryl-4- alkoxy-l, 3-butadienyl formates and acetates (from furan oxetanes) and dienyl aldehydes and ketones (from cyclic 1, 3-dienes).
