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.
![### Exercise 5.62
**Predict the products of the following reactions:**
(a) \([ \text{Pt(CO} \, \text{Cl}_3]^-\) + py →
(b)
- Structure with Pt at the center, surrounded by Cl, NO\(_2\), NH\(_3\), and Cl ligands in a square planar arrangement.
(c) \([ \text{PtCl}_3\text{SCN}]^{2-} + \text{H}_2\text{O} \rightarrow\)
(d) \([ \text{PtCl}_3\text{CN}]^{2-} + \text{NH}_3 \rightarrow\)
### Explanation:
- **Part (a):** A complex of Platinum (Pt) coordinated with carbonyl (CO) and three chloride ions (Cl\(_3\)) reacts with pyridine (py).
- **Part (b):** A square planar platinum complex with coordination:
- Two chloride ions (Cl) positioned opposite each other.
- Nitrite (NO\(_2\)) and ammonia (NH\(_3\)) as the other two ligands.
- **Part (c):** A reaction involving a platinum complex with three chloride ions and thiocyanate (SCN), mixed with water.
- **Part (d):** A platinum complex with three chloride ions and cyanide (CN) ions, reacting with ammonia (NH\(_3\)).
These reactions highlight the characteristic behaviors of coordination compounds involving ligands and transition metals, specifically platinum. The notation and structures indicate the possible substitution reactions that can occur within these complexes, a fundamental concept in coordination chemistry.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F73f287ec-1f7f-4342-bd76-a85a74415d84%2Faa073f3d-8987-442b-b974-9799b3f6f898%2F5mbnpc_processed.png&w=3840&q=75)
