3. The reaction below yields the less substituted alkene as the major product. CI N. DBU 3.1. Identify the structure of the major product (as specified above). 3.2. Give the structure of the correct stereoisomer for the reactant which would yield the product you have shown in 3.1. Outline the mechanism of the reaction starting with the correct conformation of the reactant (which resembles the transition state and satisfies the requirements of the reaction mechanism). Use curly arrows to show bond cleavage(s) and/or bond formation(s) Starting with the chair form of the cyclohexane should simplify your analysis of the mechanism. 3.3.
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.
