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