reagent was first made popular by Sven-Olov Lawesson, who did not, however, invent it. Lawesson's reagent was first made in 1956 during a systematic study...

Woollins' reagent is an organic compound containing phosphorus and selenium. Analogous to Lawesson's reagent, it is used mainly as a selenation reagent. It...

Sven-Olov Lawesson (9 September 1926, in Bräcke, Sweden – 5 March 1985) was a Swedish chemist known for his popularization of Lawesson's reagent within the...

For example, phosphorus pentasulfide (P4S10) converts anisole to Lawesson's reagent, [(CH3OC6H4)PS2]2. Also indicating an electron-rich ring, anisole...

4-dithiadiphosphetane 2,4-disulfides such as Lawesson's reagent. P4S10 is used as a thionation reagent. Reactions of this type require refluxing solvents...

sources of the dithiophosphine ylides; the most well known example is Lawesson's reagent. Other examples of this class of compound have been made; many inorganic...

highly oxophilic reagent Si2Cl6 stereospecifically deoxygenates phosphine oxides. Phosphorus pentasulfide and the related Lawesson's reagent convert certain...

chloride with an alcohol. They can also be made by the reaction of Lawesson's reagent with esters or by treating pinner salts with hydrogen sulphide. An...

is used neat, for instance the reaction of 1-bromonaphthalene with Lawesson's reagent is done with no added liquid solvent, but the 1-bromonaphthalene acts...

common. They are typically prepared by the reaction of amides with Lawesson's reagent. Isothiocyanates, with formula R−N=C=S, are found naturally. Vegetable...

first described in the 1870s. Alternative routes include the use of Lawesson's reagent or the reaction of nitriles with hydrogen sulfide: The Willgerodt-Kindler...

sulfidizing reagents such as P4S10 such as in the Paal-Knorr thiophene synthesis. Specialized thiophenes can be synthesized similarly using Lawesson's reagent as...

ketones using reagents that exchange S and O atoms. A common reagent is phosphorus pentasulfide and the related reagent Lawesson's reagent. Other methods...

obtained. Schwartz's reagent reduces amides to aldehydes, and so does hydrosilylation with a suitable catalyst. Lawesson's reagent converts amides to thioamides...
