General description
Lawesson′s试剂通常在有机合成中用作硫杂化剂，用于将氧官能团转化为其硫代类似物。其可促进羰基到硫代羰基以及碳-氧单键到碳-硫单键的转化。
Application
Lawesson试剂可用作合成以下成分的试剂：
- 通过与β--萘酚和8-羟基喹啉的曼尼希碱反应合成甲氧基苯基硫代磷环-3-硫醇衍生物。
- 在存在亚磷酸三烷基酯的条件下，通过与苯甲醛反应生成1,3,5,2-三硫代膦烷-2-硫化物衍生物。
- 从苯甲醛和丙烯酸乙酯合成2,4,6-三苯基-1,3,5-三噻烷
- 通过9-苯并蒽酮肟硫化作用合成9-苯并蒽酮硫酮。
- 从2,2,4,4-四甲基-3-硫代环丁酮 S-氧化物合成1,2,4-三硫杂环戊烷。
- 三萜氧基化合物的硫衍生物。
- 在室温下将原位捕获Tropothione并与亲二烯体一起捕获。

In the presence of Lawesson's reagent, metal-free one-pot cascade reactions of 2-iodoanilines with acid chlorides proceeded smoothly leading to 2-substituted benzothiazoles in good to excellent yields under mild conditions. Three steps were involved in the reaction process: (1) 2-iodoanilines reacted
