Thiol reduction
WebThiols can be incorporated at carboxylic acid groups by an EDAC-mediated reaction with … 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 …

WebThiol reduction proteins are key regulators of the redox state of the cell, managing … WebThe passivation of metal electrodes covered by self-assembled monolayers of long-chain thiols is well known. The disappearance of the voltammetric peak of redox species in solution is a classical test for the formation of full layers of thiols. Similar studies on semiconductors are still very limited. We used silver surfaces covered by an ultrathin layer …
