Thiol - Wikipedia 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" Many thiols have strong odors resembling that of garlic, cabbage or rotten eggs
Thioester - Wikipedia They are analogous to carboxylate esters (R−C (=O)−O−R') with the sulfur in the thioester replacing oxygen in the carboxylate ester, as implied by the thio- prefix They are the product of esterification of a carboxylic acid (R−C (=O)−O−H) with a thiol (R'−S−H)
Thiols And Thioethers – Master Organic Chemistry D There are no “thio” versions of many reactions of alcohols We’ve seen many interesting reactions that have led to alcohols and epoxides For example, treatment of alkenes with OsO 4 results in vicinal diols It’s tempting to think that there might be an analogous reaction between alkenes and OsS 4 to give vicinal dithiols
