Manufacturer: Alfa Aesar™ A1453006
Description
ApplicationsLawesson′s reagent is a thiation agent used to convert carbonyl compounds into thiocarbonyls. It is also used to thionate enones, esters, lactones, amides, lactams and quinones. Further, it is used to prepare thiols from alcohols. It is associated with silver perchlorate and utilized as and oxophilic Lewis acid catalyst for Diels-Alder reaction of dienes with alfa, beta-unsaturated aldehydes.
Solubility
Insoluble in water.
Notes
Incompatible with strong oxidizing agents.
