WebApr 5, 2024 · For example, generally, alcohol is a deprotonated form of RS –,, i.e. a thiolate. It has additional chemical reactivity than a protonated thiol from RSH. Hence, the chemistry of thiols is closely related to that of alcohols. Different forms of thiols such as thioacetals, thioether, and thioesters are equivalent to ester, ethers, and acetals.
