Organosulfur compounds

from Wikipedia, the free encyclopedia

Organosulfur compounds are a group of chemical compounds that contain an organic part and sulfur . In many compounds, the two-bonded oxygen can be replaced by sulfur. However, sulfur can also have four or six bonds. Volatile organosulfur compounds usually have an unpleasant odor.

Thionamides , thioketones , thiolesters , thionesters and thiourethanes are further examples of organic sulfur compounds. There are also numerous organic sulfur compounds that belong to the extensive group of substances called heterocycles . These include B. thiophene , thiazines , thiazoles , thiazolidines , thiazolines , thiolactams etc.

Reactions

The oxidation of a thiol leads to sulfonic acid via several intermediate stages.

Oxidation of a thiol via several intermediate steps to a sulfonic acid. This can also be done through the formation of disulfides (right path).
