Aqueous Ti(IV)-Catalyzed Diels-Alder ReactionDOI: 10.3390/12081674 Keywords: Diels-Alder reaction, aqueous, cyclohexadiene, benzoquinone, Lewis acid catalysis, green chemistry, water-soluble Lewis acid catalyst. Abstract: The aqueous Diels-Alder reaction of 1,3-cyclohexadiene with 1,4-benzoquinone was compared and contrasted to the same reaction catalyzed with Flextyl P?, a novel Ti(IV) performance catalyst. The catalyst improved conversion by 22% versus the uncatalyzed reaction and represents a rare example of a Ti(IV) catalyzed Diels-Alder reaction in water.
