The first Diels-Alder reaction of vinyl arenes with ene systems catalyzed by MOFs is reported. Maleimides and maleic anhydride were annulated/dehydrogenated on styrenes in the presence of a mixed-metal (FeNi)MIL-88A catalyst. Neither an additional oxidant nor a source of halogen is needed to drive this oxidative [4 + 2] cyclization reaction. Kinetic evidence such as activation entropy corroborates the proposed concerted mechanism. The reaction proceeds merely through a cost-effective catalyst in water as the greenest solvent. The product of annulation of styrene with maleic anhydride was used for the first L-selective annulative π-extension on naphthalene.

A method for purifying a dimethyl naphthalene dicarboxylate produced from a naphthalene dicarboxylic acid which is in turn produced by the liquid phase oxidation of a dialkylnaphthalene or partially oxidized derivative thereof in the presence of a catalyst comprising a bromine-containing component and at least one of a cobalt- or manganese-containing component.
