• Lawesson's 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 of the reactions of arenes with P 4 S 10.
• Prof T . B . Rauchfuss, who is in the United States did some very important work on Lawesson's reagent.
• Lawesson's reagent has been used as a starting material for a herbicide by reaction with a 1-alkoxy-2, 3-dihydroxy propane.
• Synthesis of a thiophene requires a sulfurizing agent which is typically a sufficient dehydrator, such as phosphorus pentasulfide, Lawesson's reagent, or hydrogen sulfide.
• In one type of solventless reaction a liquid reactant is used 1-bromonaphthalene with Lawesson's reagent is done with no added liquid solvent, but the 1-bromonaphthalene acts as a solvent.
• A combination of silver perchlorate and Lawesson's reagent is able to act as an oxophilic Lewis acid with the ability to catalyze the Diels-Alder reaction of dienes with ?, ?-unsaturated aldehydes.
• As Lawesson's reagent has a strong and unpleasant smell, it is best to prepare the compound within a fume-hood and to treat all glassware used with a decontamination solution before taking the glassware outside the fume-hood.
• This reaction of a 1, 2-diol with lawesson's reagent results in a symmetric breaking of the P 2 S 2 ring, both halves of the lawesson's reagent end up being converted to the same product.

• It has been proven in recent times by the reaction of diferrocenyl 1, 3, 2, 4-dithiadiphosphetane 2, 4-disulfide ( and Lawesson's reagent ) with dimethyl cyanamide that in fact a mixture of several different phosphorus containing compounds is formed.
• It has been proven in recent times by the reaction of diferrocenyl 1, 3, 2, 4-dithiadiphosphetane 2, 4-disulfide ( and Lawesson's reagent ) with dimethyl cyanamide that, in fact, a mixture of several different phosphorus-containing compounds is formed.
• In general NpP 2 S 4 has been found to be less reactive than Lawesson's reagent, this result agrees with the hypothesis that the dithiophosphine ylides are responsible for the majority of the chemical reactions of the 1, 3, 2, 4-dithiadiphosphetane 2, 4-disulfides.
• A compound related to Lawesson's reagent named "'NpP 2 S 4 "'has been formed by the reaction of 1-bromonaphthalene with P 4 S 10, this is a 1, 3, 2, 4-dithiadiphosphetane 2, 4-disulfide which has a naphth-1, 8-diyl group holding the two phosphorus atoms together.
