Concept introduction:
Catalytic hydrogenation is the addition of two atoms of hydrogen to a double bond. A compound with two double bonds undergoes catalytic hydrogenation, then there will be addition of four atoms of hydrogen.
This reaction occurs in the presence of platinum, palladium, nickel, or rhodium. One molar equivalent of hydrogen, when added to
Conjugated dienes contain two

- Classify the following diene, as an aid to understanding its reactivity. H,C=C%3DCH, Conjugated Diene Cumulated Diene O Isolated Diene None of the above classifications is accurate.arrow_forwardWhich of the following statments is TRUE about the Diels-Alder cycloaddition reaction? The best reactions occur with an electron-rich diene and an electron-poor dienophile. The reaction favors the exo-product. Entropy drives the reaction toward the cyclohexene product. The reaction is not stereospecific with respect to the dienophile stereochemistry.arrow_forwardOne step in the synthesis of dodecahedrane involves reaction of the tetraene C with dimethylacetylene dicarboxylate (D) to afford two compounds having molecular formula C16H16O4. This reaction has been called a domino Diels–Alder reaction. Identify the two products formed.arrow_forward
- Dimethyl azodicarboxylate takes part in a DielsAlder reaction as a dienophile. Write the structure of the cycloaddition product of this molecule with 1,2-dimethylenecyclohexane. Knowing that this compound is formed under mild conditions, explain what favors reactivity in a Diels-Alder reaction over diene and dienophile structures.arrow_forwardDraw the structures of the diene and dienophile that would be used in the diels alder reaction to synthesize the following compounds. Label each structure as diene or dienophile.arrow_forwardThe Diels–Alder reaction between butadiene and dimethyl maleate yields a ring structure, as shown in the product. Complete the structure by drawing any missing bonds and indicating the stereochemistry of the new stereocenters.arrow_forward
- 4. Give the structure of a conjugated diene with the molecular formula of C7H12.arrow_forwardWhat represents the structure of the diene to carry out the following Diels-Alder reaction?arrow_forwardDraw structural formulas for the diene and dienophile that combine in a Diels-Alder reaction to form the product shownarrow_forward
- The Wittig reaction can be used for the synthesis of conjugated dienes as the example below, 1-phenyl-penta-1, 3-diene. Propose two different sets of reagents that could be combined in a Wittig reaction to give 1-phenyl-1,3-pentadiene.arrow_forwardAlthough the Diels–Alder reaction generally occurs between an electronrich diene and an electron-deficient dienophile, it is also possible to have inverse-demand Diels–Alder reactions between suitable electrondeficient conjugated double bonds and electron-rich alkenes. These reactions are particularly useful because they allow for the incorporation of heteroatoms into the new six-membered ring. Predict the products of each inverse-demand Diels–Alder reaction below. Be sure your products reflect the correct stereochemistry. If more than one regioisomer is possible, draw both.arrow_forwardHydrohalogenation of alkenes in the presence of peroxide adds a halide at the vinyl position. Which halide can be used in UV-catalyzed hydrohalogenation reaction in the presence of diethyl ether to obtain alkyl halide. Note: Distillation of the diethyl ether used in the reaction resulted in a violent explosion. * Molecular fluorine, only molecular bromine, only Molecular chlorine only molecular iodine, only Bromine and Molecular Chlorine, only naharrow_forward
