The methods suitable for the preparation of thiocarbamates are described and illustrated by examples and procedures. They are grouped under the following headings: Addition of Alcohols and Thiols to Isothiocyanates Thioacylation of Amines with chlorothioformates with O,S‐diesters of dithiocarbonic acid with trithiocarbonates Thioacylation of Alcohols, Phenols, and Thiols with thiocarbamoyl chlorides with N,N‐dialkylmercaptochloroformimidium chlorides with N,N′‐thiocarbonyldiimidazole Reaction of Thiocyanates and Cyanates with Hydrogen Sulfide Alkylation of Metal Dithiocarbamates Additions to Thiocyanic Acid

Methods for the preparation of thiocarboxamides are described with special reference to progress achieved in the last few years. The discussion is arranged according to the eight most important reaction types. Reaction of nitriles with hydrogen sulfide and thiolsReaction of imidic acid derivatives with hydrogen sulfide and thiols Sulfurization of amides Addition of nucleophiles t o isothiocyanates

Ist das C‐Atom der Thioamidgruppe mit einem elektronenanziehenden Rest verknüpft, so entstehen nur dann stabile S‐Oxide, wenn eine unsubstituierte oder allenfalls eine mono‐ substituierte Thioamidgruppe vorliegt. Im letzteren Falle müssen Einflüsse wirksam sein, welche den Elektronenbedarf am C‐Atom der Thioamidgruppe vermindern.
