Provide mechanistic pathway for each step and the products based on the reagents selected. Diels Alders reactions to consider the formation of the products stated below. Product in step 1 is used for step 2. Product instep 2 is used for step 3. Indicate any required stereochemistry (E, Z, R, S). Step 1: 3-bromo-3-methylbut-1-ene with sodium ethoxide Step 2: addition of maleic anhydride and heat Step 3: hydrogen gas bubbling with palladium metal
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.
