- Draw the products of the attached Diels–Alder reactions. Indicatestereochemistry where appropriate.Consider the following dienes in a Diels–Alder reaction with ethene. Which will react the fastest? Which will react the slowest? ExplainRank the following dienophiles in order of increasing reactivity.
- A.) Draw two schemes, For the first scheme combine A and B. For the second, combine A and C. b.) For each scheme predict all products. c.) Label the major and minor products d.) Show all stereochemical configurations in the products, give reasons regarding sterochemical outcomes for each rxn. e.) Propose an appropriate solvent for each scheme, give a reason. f.) Discuss what by what mechanism your products are formed and why. (SN2, E2, E1, SN1)To make Halocyclopentane, what reagents and substartes are needed? Which one(below) is related with the Halocyclopentane? Esterification, Alcohol Halogenation ,Alkyl Halide Solvolysis, Alkene Hydration, Hydroboration, Alkene Bromination, Alkene Dihydroxylation, Epoxidation, Diels Alder, Aldol, Grignard Addition, Benzene Nitration, Friedel-Crafts, Carbonyl Reduction, Claisen Condensation, Alcohol OxidationThe molecule in the box is the product of a diels alder reaction. Which of these is the dienophile in that reaction ? A B C D or E?
- Intramolecular Diels–Alder reactions are possible when a substrate contains both a 1,3-diene and a dienophile, as shown in the following general reaction.With this in mind, draw the product when each compound undergoes an intramolecular Diels–Alder reaction.What diene and dienophile are needed to prepare attached compound by aDiels–Alder reaction?For 1 and 2, identify the predominant type of reaction: SN1, SN2, E1 and E2. Draw the major products only. Show stereochemistry whenever applicable.
- Internal alkynes are able to selectively form one product when subjected to most reaction conditions. T or F Alkynes react with one equivalent of acid to create a carbocation for Markovnikov addition. T or F Alkynes react very similarly to alkenes. Understanding the mechanisms from chapter 12 will help understand the reaction pathways in chapter 13 where mechanisms are not explicitly drawn. T or FFor this mechanism, why are there two E1 major products? Are both of the E1 products of equal stability? Why or why not? What is the relative stability of the cycloalkenes with methyl? Also, why doesn't SN1 have two products? Is it because shifting the hydride would make it less stable?What two sets of a conjugated diene and a dienophile could be used to prepare the following compound?
