Description
- 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.[1][2][2]
- 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.[3]1,3,5,2-Trithiaphosphinane-2-sulfide derivatives by reacting with benzaldehyde in the presence of trialkyl phosphite.[3]2,4,6-Triphenyl-1,3,5-trithiane from benzaldehyde and ethyl acrylate.[3]9-Benzanthronethione by thionation of 9-benzanthone oxime.[2]1,2,4-Trithiolane from 2,2,4,4-tetramethyl-3-thioxocyclobutanone S-oxide.[4]Sulfur derivatives of triterpenic oxo compounds.[5]Tropothione in situ at room temperature and to trap it with dieneophiles.[6]
