Popis:	The benzophenone sensitized photocycloaddition of 2,3-dimethylmaleimide to selenophene and 3,4-dimethylselenophene was carried out first to generalize the photoaddition reaction of methylmaleic anhydride derivatives to selenophene, using this time the nitrogen analogue, and second to reexamine the composition of the product mixture formed in the reaction. It was found that in adition to the 1:1 adduct isolated in previous investigations, three geometrical isomers may be proposed for the 2:1 adduct (two molecules of maleimide of one of selenophene or its methyl derivative).
