3 sulfolene and maleic anhydride reaction

It was easier to start with solid 3-sulfolene and then decompose it, rather than starting with gaseous 1,3-butadiene (Fig 1) The dienophile, maleic anhydride, attacks the diene forming 4- cyclohexene-cis-dicarboxylic anhydride (Fig + FIGURE 1 The decomposition of 3-sulfolene to produce 1,3-butadiene

24 juil 2006 · Maleic anhydride causes burns Avoid contact • Attach apparatus to a water trap like Experiment #3 The sulfolene decomposes to form butadiene and sulfur dioxide Butadiene will react with maleic anhydride and the sulfur dioxide will bubble out of solution

In this experiment, 3-sulfolene will be heated in the presence of the dienophile maleic anhydride The released butadiene from the retro Diels-Alder reaction will
