Take the time to validate and double check the source of the data. The purpose of this experiment is to form 9,10-dihydroanthracene-9,10-α,β-succinic anhydride by way of a Diels Alder reaction between anthracene and maleic anhydride, as shown in the reaction below. Anthracene acts as the diene and maleic anhydride functions as the dienophile.
1 Jan 2011 This year we reacted the anthracene diene with two different The Bruice Organic Chemistry textbook has the Diels-Alder reaction in two different dienophiles in addition to the classic maleic anhydride. The expec
The reaction involves three π bonds, two from the diene and one from the dienophile in a concerted reaction to form a six-membered ring. Since the reaction involves four π electrons in the diene and two π electrons from the dienophile, it is sometimes referred to as a 4 + 2 cycloaddition.

In the same fashion anthracene (diene) reacts with maleic anhydride product commonly known as “adduct” and reaction is known as Diels- Alder reaction. Place 1.0 g of anthracene and 0.5 g of maleic anhydride in a 100-mL round- bottom flask. Add 15. mL of xylene and a boiling chip. Attach a reflux condenser to the
I'm wondering why maleic anhydride adds to the middle cycle of anthracene, and not the outer two. Reaction of anthracene with maleic anhydride.

The Diels-Alder reaction is a member of a class of reactions called cycloadditions. The reaction involves three π bonds, two from the diene and one from the dienophile in a concerted reaction to form a six-membered ring. Since the reaction involves four π electrons in the diene and two π electrons from the dienophile, it is sometimes referred to as a 4 + 2 cycloaddition. Although there are four stereogenic centres in the product only two diastereoisomers can be formed, any others are impossibly strained.

The Diels–Alder reaction is the reaction between a conjugated diene and an alkene (dienophile) to form unsaturated six-membered rings. Since the reaction involves the formation of a cyclic product via a cyclic transition state, it is also referred to as a
Anthracene was the diene and maleic anhydride was the dienophile.
