Chapter 22, Problem 22.51P
Interpretation Introduction

Interpretation:

The mechanism for the given reaction is to be proposed.

Concept introduction:

Benzene undergoes electrophilic-aromatic substitution reactions in which the hydrogen atom in the aromatic system is replaced by an electrophile. Carbon atoms in epoxides are not electrophilic, but they can be made electrophilic if the catalyst AlCl3 is used. Note that the reaction does not take place without the presence of aluminum chloride. The oxygen atom attacks the electropositive aluminum in aluminum chloride to form a complex. This generates carbon electrophile. Thus, the epoxide ring can be opened by weak nucleophiles like benzene. Aluminum chloride is regenerated, so it is a catalyst. The proton transfer reaction regenerates the aromatic ring, and alcohol is formed as the major product.

I have a question about this problem involving mechanisms and drawing curved arrows for acids and bases. I know we need to identify the nucleophile and electrophile, but are there different types of reactions? For instance, what about Grignard reagents and other types that I might not be familiar with? Can you help me with this? I want to identify the names of the mechanisms for problems 1-14, such as Gilman reagents and others. Are they all the same? Also, could you rewrite it so I can better understand? The handwriting is pretty cluttered. Additionally, I need to label the nucleophile and electrophile, but my main concern is whether those reactions differ, like the "Brønsted-Lowry acid-base mechanism, Lewis acid-base mechanism, acid-catalyzed mechanisms, acid-catalyzed reactions, base-catalyzed reactions, nucleophilic substitution mechanisms (SN1 and SN2), elimination reactions (E1 and E2), organometallic mechanisms, and so forth."
