Mechanism 3. When heated the cyclobutene below coverts to a mixture of products A and B. The ftirst step of each of the two mechanisms is very similar, but not exactly the same. Following the first step the reactions follow very different paths. Provide separate mechanisms for the formation of A and B. Briefly explain what is happening in the first step of the mechanism and why the pathway to B cannot following the same or similar mechanism as the path to A. CDC, 100 °C mechanism: explain:
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.
