A
thioether is a functional group in
organosulfur chemistry with the connectivity C-S-C as shown on right. Like many other sulfur-containing compounds,
volatile thioethers have foul odors. A thioether is similar to an
ether except that it contains a sulfur atom in place of the oxygen. The grouping of oxygen and sulfur in the
periodic table suggests that the chemical properties of ethers and thioethers are somewhat similar.
