The title compound was prepared in two steps by [2 + 2] photochemical cycloaddition between (E)-1,2-dichloroethene and maleic anhydride followed by reductive chlorine elimination with activated zinc. This safe synthetic route gave cis-cyclobut-3-ene-1,2-dicarboxylic anhydride in good overall yield and could be carried out on a multigram scale.
