Reactions of Ethers

Ethers (R-O-R’) are compounds formed by replacing hydrogen atoms of an alcohol (R-OH compound) or a phenol (C6H5OH) by an aryl/ acyl group (functional group after removing single hydrogen from an aromatic ring). In this section, reaction, preparation and behavior of ethers are discussed in the context of organic chemistry.

Epoxides

Epoxides are a special class of cyclic ethers which are an important functional group in organic chemistry and generate reactive centers due to their unusual high reactivity. Due to their high reactivity, epoxides are considered to be toxic and mutagenic.

Williamson Ether Synthesis

An organic reaction in which an organohalide and a deprotonated alcohol forms ether is known as Williamson ether synthesis. Alexander Williamson developed the Williamson ether synthesis in 1850. The formation of ether in this synthesis is an SN2 reaction.

Question

**3. Reaction Mechanism Involving an Alkene and Br₂**

When the alkene A was treated with Br₂, the product formed was the epoxide B. Using curved arrows, please provide the mechanism of this reaction, including any regioselectivity or stereoselectivity.

**Diagram Explanation:**

1. **Left Structure (Alkene A):**
- This structure shows a bicyclic alkene with a double bond. The alkene is symmetrical and part of a larger cyclic system.
- There are dashed lines representing stereochemical orientation.

2. **Arrow Indicating Reaction:**
- The alkene reacts with Br₂ (bromine) in the presence of water (H₂O), indicated by an arrow pointing to the right, showing the formation of the product.

3. **Right Structure (Epoxide B):**
- The product is an epoxide, characterized by a three-membered cyclic ether.
- There is an oxygen atom bonded in the epoxide ring where one bromine would typically attach.
- The stereochemistry is indicated by wedged and dashed lines.

**Graphical Note:**
The curved arrows, though not shown, represent electron movement critical for illustrating the reaction mechanism.

1. Cl₂, H₂O 2. NaOH Another mechanism for the formation of epoxides is through the formation of a chlorohydrin. Alkenes react with chlorine in the presence of H₂O to give a chlorohydrin via a cyclic chloronium ion intermediate. When the chlorohydrin is treated with strong base, HCI is eliminated and the epoxide is formed. Draw curved arrows to show the movement of electrons in this step of the mechanism.
