Rank the following dienes from most reactive to least reactive in a Diels Alder reaction. please explain steps
Rank the following dienophiles in their rate of reaction with the same diene in a Diels-Alder reaction. For example, 1 = fastest or most reactive dienophile, 4 = slowest or least reactive dienophile.
Rank the following dienes in order of their reactivity in standard Diels-Alder reactions (1= most reactive, 4= least reactive). Be sure to briefly explain your choices.
This is a Diels-Alder reaction between furan + maleic anhydride (endo and exo products). For each cycloaddition product, draw in all hydrogen atoms, and write the molecular formula below.
what is the product after these compumds undergo a diels-alder reaction
Draw a Diels-Alder reaction that shows the stereospecificity of the reaction with respect to both the diene and dienophile, and that would follow the endo rule (show only the major product).
A Diels-Alder reaction that shows regioselectivity, but not stereoselectivity
Rank the following dienes in order of increasing reactivity in a Diels-Alder reaction.
Is this the correct order and conditions to produce the diels-alder product on the right? Thank you
Diels–Alder reaction of a monosubstituted diene (such as CH2=CH–CH=CHOCH3) with a monosubstituted dienophile (such as CH2=CHCHO)gives a mixture of products, but the 1,2-disubstituted product oftenpredominates. Draw the resonance hybrid for each reactant, and use thecharge distribution of the hybrids to explain why the 1,2-disubstitutedproduct is the major product.
Rank the following dienes from most reactive to least reactive in a Diels–Alder reaction:
This is a Diels-Alder reaction between cyclopentadiene and maleic anhydride (endo and exo products). For each cycloaddition product, draw in all hydrogen atoms, and write the molecular formula below.
