Diels Alder Reaction of Tetraphenylcyclopentadienone Purpose of the Experiment: To successfully synthesize dimethyltetraphenylphthalate via a Diels Alder reaction. The melting point of the product is 258oC. Why should we not do a melting point of the product? The intermediate in brackets loses CO to form the product at 180oC. If the C=O were replaced by CH2, do you think the same type of reaction would happen with loss of :CH2?

Uemura and coworkers studied a time dependent Diels-Alder reaction which first formed the endo product as the major organic product and with time produced the exo product (J. Org.

1,4-Benzoquinone is a good Diels–Alder dienophile. Predict the products of its reaction with(a) buta-1,3-diene
1)Chemistry students are taking an experimental course in organic chemistry at a public university. During an experiment involving conjugated dienes, some doubts arose when discussing the results obtained so far: (a) A student obtained two products from the reaction of 1,3-cyclohexadiene with Br2. His lab partner was surprised to get only one product from the reaction of 1,3 - cyclohexadiene with HBr. Explain these distinct results. (b) One student, seeing the discussion of colleagues, commented that she obtained two distinct products when reacting 1,3,5-hexatriene with HBr, with different yields just by changing the reaction temperature. Explain the results she obtained using reaction mechanism and based on kinetic and thermodynamic control involving conjugated dienes.
A chemist wanted to determine experimentally the relative ease of removing a hydrogen atom from a tertiary, a secondary, and a primary carbon by a chlorine radical. He allowed 2-methylbutane to undergo chlorination at 300 °C and obtained as products 36% 1-chloro-2-methylbutane, 18% 2-chloro-2-methylbutane, 28% 2-chloro-3-methylbutane, and 18% 1-chloro-3-methylbutane. What values did he obtain for the relative ease of removing a hydrogen atom from tertiary, secondary, and primary hydrogen carbons by a chlorine radical under the conditions of his experiment?

This problem is adapted from an experiment designed for undergraduate organic chemistry laboratories. (a) Reaction of (E)-1-(p-methoxyphenyl)propene with m-chloroperoxybenzoic acid converted the alkene to its corresponding epoxide. Give the structure, including stereochemistry, of this epoxide.(b) Assign the signals in the 1H NMR spectrum of the epoxide to the appropriate hydrogens. δ 1.4 (doublet, 3H) δ 3.8 (singlet, 3H) δ 3.0 (quartet of doublets, 1H) δ 6.9 (doublet, 2H) δ 3.5 (doublet, 1H) δ 7.2 (doublet, 2H) (c) Three signals appear in the range δ 55–60 in the 13C NMR spectrum of the epoxide. To which carbons of the epoxide do these signals correspond? (d) The epoxide is isolated only when the reaction is carried out under conditions (added Na2CO3) that ensure that the reaction mixture does not become acidic. Unless this precaution is taken, the isolated product has the molecular formula C17H17O4Cl. Suggest a reasonable structure for this product and write a reasonable mechanism…
An experiment of synthesising ferrocene using potassium hydroxide and 1,2-dimethoxyethane reacted with freshly cracked cyclopentadiene was carried out. Before the addition of a solution containing iron(II) chloride tetrahydrate in DMSO to the first solution, the solution in the round bottom flask had greatly reduced in volume and had turned red in colour before adding any of the iron(II) chloride tetrahydrate in DMSO. What could be the possible reason for this? Explain why this had happened in detail. NOTE: The total yield was very low of ferrocene product.
The following excerpt is a commonly used lab procedure for a Diels-Alder reaction. Provide three specific reasons why the one here would not be classified as a green chemistry option compared to ours. Be sure to reference and explain the principles of green chemistry to support your response. excerpt- Place 2 g of maleic anhydride in a 50-mL Erlenmeyer flask and dissolve it in 8 mL of ethyl acetate by warming on a hot plate. Add 8 mL of hexane or petroleum ether, and then cool the solution in an ice bath. Obtain 2 mL freshly cracked cyclopentadiene and add it to the maleic anhydride solution. Swirl to mix. Wait until the product crystallizes from solution, then heat it on the hot plate to redissolve, and allow it to recrystallize. Collect the product by suction filtration, and record the melting point, weight, and percentage yield.
