Decarboxylative Dimerization of maleic Anhydride to Dimethylmaleic Anhydride We have found a simple synthesis of dimethylmaleic anhydride ( 1 ). Treatment of maleic anhydride ( 2 ) in boiling acetic acid in presence of 2‐aminopyridine gives, with decarboxylation, 1 in a one‐pot reaction in good yield.
