Lawessons reagent sigma
WebAmong the various thionating reagents, Lawesson's reagent was found to be most suitable and showed versatile properties, including chemoselectivity and functional group tolerance. In this review, we present the role of Lawesson's reagent in the synthesis of thioanalogues of natural steroids and terpenoids. Lawessons Reagenz hat sich als äußerst nützlich für die Herstellung von Thiocarbonylverbindungen aus Carbonylverbindungen erwiesen. Es ist reaktiver als Phosphor(V)-sulfid, P4S10, und bei höherer Temperatur ausreichend in organischen Lösungsmitteln löslich, so dass die Reaktionen in einer homogenen Lösung durchgeführt werden können. Lactame lassen sich mittels …

WebLawesson's reagent. Lawesson's reagent, or LR, is a chemical compound used in organic synthesis as a thiation agent. 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. WebThionations of carbonyl-containing compounds as well as unexpected reactions are shown for different applications (e.g. cyclizations, rerrangements, syntheses of heterocyclic compounds etc.). Syntheses of novel organometallic compounds by LR are also discussed. 1 Introduction. 2 Mechanism of the Thionation Reaction Using Lawesson's Reagent. 3 ...
