In organic chemistry, an organic sulfide (British English sulphide) or thioether is an organosulfur functional group with the connectivity R−S−R' as shown on right. Like many other sulfur-containing compounds, volatile sulfides have foul odors. A sulfide 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 sulfides are somewhat similar, though the e… WebThe S 6 crown thioether (111) forms a low-spin octahedral complex by reaction with cobalt(II) picrate in refluxing acetone/acetonitrile for a short period, and is one of the few …
