Background:
As you learned in this Module , the [4 +2]-cycloaddition of a conjugated diene with 4 π-electrons and a dienophile (an alkene or an alkyne) with 2π-electrons—commonly known as the Diels–Alder reaction—is one of the most famous pericyclic reactions due to its easy synthesis that is regio- and stereoselective.
Instructions:
Read the Open Access Journal Article:
Diels–Alder reactions and electrophilic substitutions with atypical regioselectivity enable functionalization of terminal rings of anthracene.
Download Diels–Alder reactions and electrophilic substitutions with atypical regioselectivity enable functionalization of terminal rings of anthracene
Discuss the following questions with your classmates:
1.What are anthracenes? What are olefins? What Are they used for?
2.How are anthracenes used by the researchers who wrote the article?
3.How can anthracenes be activated or deactivated towards the Diels Alder Reaction?
4.What electron-donating and electron-withdrawing groups are used in the research experiments?
5.How did the electron-donating substitution affect the reactivities of anthracenes when compared to unsubstituted anthracene? Explain.
6.What is the conclusion of this research study? What is a novel finding?
Be sure to post an initial, substantive response by Thursday at 11:59 p.m. MT, and respond to two or more classmates or the instructor with substantive responses by Sunday at 11:59 p.m. MT.
A substantive initial post answers the question presented completely and/or asks a thoughtful question pertaining to the topic. Be sure your post is unique.
Dear students,
This week we cover Diels–Alder reactions. I highly encourage you to watch the following video to better understand this topic:
