• ThiolsThiols (R–S–HR–S–H) and sulfidessulfides (R–S–R’R–S–R’) are sulfur analogs of alcohols and ethers, respectively

– Sulfur replaces oxygen

77.. Thiols and SulfidesThiols and Sulfides

• ThiolsThiols (RSHRSH), also known as mercaptans, are sulfur analogs of alcohols

– They are named with the suffix ––thiolthiol– SHSH group is called “mercapto groupmercapto group” (“capturer of

mercury”)

SulfidesSulfides

• SulfidesSulfides (RSR’RSR’) are sulfur analogs of ethers

– They are named by rules used for ethers, with sulfidesulfide in place of etherether for simple compounds and alkylthioalkylthio in place of alkoxyalkoxy
