WebPhenyllithium wird in der organischen Chemie für eine Reihe von Synthesen (zum Beispiel bei der Bildung von Biphenylen durch nucleophile aromatische Substitutionen) eingesetzt. Es liegt dazu in technischer Form als geringprozentige Lösung (üblich etwa 20 %) in verschiedenen Lösungsmitteln wie Di- n -butylether, Cyclohexan /Ether vor. WebProduction. Organolithium reagents are industrially prepared by the reaction of an halocarbon with lithium metal, i.e. R-X + 2 Li → R-Li + LiX. A side reaction of this synthesis, especially with alkyl iodides, is the Wurtz reaction, in which an R-Li species reacts with an R-X species forming an R-R coupled product.This side reaction can be almost completely …
