What happens when furan reacts with maleic anhydride?
Furan and maleic anhydride were converted to phthalic anhydride in two reaction steps: Diels–Alder cycloaddition followed by dehydration. Phthalic anhydride is used for the manufacture of plasticizers, unsaturated poly- esters, and alkyd resins.
What happens when anthracene react with maleic anhydride?
Anthracene acts as the diene and maleic anhydride functions as the dienophile. Xylene (dimethylbenzene) is used as a high boiling temperature solvent so that the reaction will proceed quickly . In this experiment, you will • Synthesize 9,10-dihydroanthracene-9,10-α,β-succinic anhydride.
When furan and maleic acid react with each other which reaction takes place?
DIELS-ALDER MECHANISM It is a concerted cyclization reaction which generates an adduct of the starting diene (furan) and dienophile (maleic anhydride) that contains two new C−C bonds.
Which reagents is use from 9 10 dihydro anthracene from anthracene?
9,10-Dihydro-anthracene-9,10-α,β-succinic anhydride 3 has been synthesized by reaction of anthracene 1 and maleic anhydride 2 (Scheme 1) under conventional heating 38.
Is Diels Alder reaction a cycloaddition?
A cycloaddition reaction is the concerted bonding together of two independent pi-electron systems to form a new ring of atoms. The Diels-Alder cycloaddition is classified as a [4+2] process because the diene has four pi-electrons that shift position in the reaction and the dienophile has two.
What are the cycloaddition reactions of 9 substituted anthracene?
The first repoorted cycloaddition reactions of 9-substituted anthracene in this area cycloaddition reactions of 9-anthraldehyde with maleic anhydride, acrylic acid, acrylonitrile and allyl alcohol to assess its reactivity and selectivity with these dienophiles.
Which is the diene anhydride in anthracene?
Anthracene acts as the diene and maleic anhydride functions as the dienophile. Xylene (dimethylbenzene) is used as a high boiling temperature solvent so that the reaction will proceed quickly . In this experiment, you will Synthesize 9,10-dihydroanthracene-9,10-α,β-succinic anhydride.
