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.
Reagents are chemical reaction of speed low and high.
Step1--alchol convert to alkyl halide the reagents are use of hydrogen bromide(HBr).
step2-first of the alkyl halide reaction are nitrile group (CN) than after reaction of hydrolysis of alkyl nitrile group the formation are carboxlic acid.
step3-carboxlic acid to Ester formation of esterificatition chemical reaction.
These chemical reaction are carboxlic acid react of alkyl alchol it a presence of cons.H2SO4.
