It is the anhydride of 2,3-dimethylmaleic acid. Synthesis The compound can be prepared from two equivalents of MA in the presence of various amines, such as 2-aminopyridine, followed by treatment with sulfuric acid.10.1002/hlca.19840670728 Mechanismus der decarboxylativen Dimerisierung von Maleinsäureanhydrid zu Dimethylmaleinsäureanhydrid unter Einfluss von 2-Aminopyridin 1984 Baumann Marcus E.
