1 3 cyclohexadiene and maleic anhydride product name
Which cyclopentadiene is a good dienophile for a Diels-Alder reaction?
Cyclopentadiene is held in the required s-cis configuration so it will make a good diene for a Diels-Alder reaction. Maleic anhydride is also a very good dienophile, because the electron-withdrawing effect of the carbonyl groups causes the two alkene carbons to be electron-poor, and thus a good target for attack by the pi electrons in the diene.
What is the difference between cyclic diene and cyclohexene?
Cyclic dienes, on the other hand, are ‘locked’ in the s-cis conformation, and are especially reactive. The result of a Diels-Alder reaction involving a cyclic diene is a bicyclic structure: The 1 and 4 Carbons in the diene have the possibility of forming two new stereocenters in the cyclohexene product.
What happens when cyclopentadiene and maleic anhydride react?
The dienophile has two nitriles attached to it both of which are electron withdrawing. Since the two nitriles in the dieneophile are cis to each other the the two nitriles will be cis to each other in the product. A particularly rapid Diels-Alder reaction takes place between cyclopentadiene and maleic anhydride.
Does maleic anhydride have a head and a tail?
Maleic anhydride does have a “head” and a “tail”, unlike ethylene. The two approaches of cyclopentadiene to maleic anhydride are therefore not equivalent, which results in two different transition states ( diastereomeric transition states) which leads to two different products. [ Note 3] This is the origin of endo and exo! 10.
