Thiol reduction

WebThiols are the sulfur analogs of alcohols (Section 15.11).The sulfur atom of a thiol is a better nucleophile than the oxygen atom of an alcohol. Thus, thiols react with aldehydes or ketones to form thioacetals or thioketals by a mechanism similar to that described for acetals and ketals. These sulfur derivatives form in high yield because the equilibrium constant for … WebThiols (RSH) are prepared by relying on the high nucleophilicity of sulfur. For example, the reaction of sodium hydrosulfide with unhindered alkyl halides is the most common approach for preparing thiols. Because of the high nucleophilicity of the thiol, the hydrosulfide is used in a large excess to prevent it from reacting with the alkyl ...

In organic chemistry, a thiol , or thiol derivative, is any organosulfur compound of the form R−SH, where R represents an alkyl or other organic substituent. The −SH functional group itself is referred to as either a thiol group or a sulfhydryl group, or a sulfanyl group. Thiols are the sulfur analogue of alcohols (that is, sulfur takes the place of oxygen in the hydroxyl (−OH) group of an alcohol), and the word is a blend of "thio-" with "alcohol".
