General description
Lawesson′s reagent is generally used as a thiation agent in organic synthesis for the conversion of oxygen functionalities into their thio analogs. It facilitates the conversion of the carbonyl group to thiocarbonyl group as well as carbon-oxygen single bond into a carbon-sulfur single bond.
Application
Lawesson reagent can be used as a reagent to synthesize:
- Oxthiaphosphinine-3-sulfide derivatives by the reaction with Mannich bases of β-naphthol and 8-hydroxyquinoline.
- 1,3,5,2-Trithiaphosphinane-2-sulfide derivatives by reacting with benzaldehyde in the presence of trialkyl phosphite.
- 2,4,6-Triphenyl-1,3,5-trithiane from benzaldehyde and ethyl acrylate.
- 9-Benzanthronethione by thionation of 9-benzanthone oxime.
- 1,2,4-Trithiolane from 2,2,4,4-tetramethyl-3-thioxocyclobutanone S-oxide.
- Sulfur derivatives of triterpenic oxo compounds.
- Tropothione in situ at room temperature and to trap it with dieneophiles.
