Why is it important that the 3 Sulfolene and maleic anhydride are fully dissolved before heating the reaction mixture to reflux?
5) Why should 3-sulfolene and maleic anhydride be completely dissolved in xylene before heating the mixture to effect reaction? Both reactants should be completely dissolved before heating because the 3-sulfolene must decompose to form butadiene.
Why is 3 Sulfolene rather than 1/3 butadiene itself to be used as a source of the diene?
3-Sulfolene as an alternative reactant for 1,3-butadiene in diene syntheses has the following advantages: (1) it is practically nontoxic and presents no particular flammability hazard; (2) it is an odorless, crystalline, nonhygroscopic solid which may be stored without inhibitor at ordinary temperatures for years with …
What are Dienophiles?
Definition of dienophile : the olefinic or acetylenic component (such as maleic anhydride) that is seeking a diene in the Diels-Alder reaction.
