Reaction between thiol and alcohol
WebThiols can be oxidized or be part of disulfide bonds in proteins and thus need to be freshly reduced with reducing agents such as DTT, which must then be removed from the protein before reaction with the thiol-reactive dye to avoid competition between thiol of DTT and the cysteine residue. WebThe Mitsunobu Reaction allows the conversion of primary and secondary alcohols to esters, phenyl ethers, thioethers and various other compounds. The nucleophile employed should be acidic, since one of the reagents ( DEAD, diethylazodicarboxylate) must be protonated during the course of the reaction to prevent from side reactions.

In contrast, thiols are more acidic than alcohols because the S–H bond is weaker—the size of S and H orbitals results in smaller overlap and therefore weaker bonds (just like HBr is more acidic than HCl) and the resulting anion is more stable because the larger size of S results in the negative charge being … See more Recall that there are several factors that can influence Brønsted acidity. These include: the strength of the bond between the R (C) and the O, S, or N (denoted by “Y” below) and H; the polarity of the bond; and the stability of the … See more Earlier (Chapters 1 and 4), we discussed (at great length) that all three functional groups (–OH, –NH, and –SH) are nucleophilic: that is, they will react at the carbon center that is … See more Before we discuss oxidation of alcohols, it should be clear what we mean by the “oxidation” and “reduction” of carbon compounds.
