Anwendungen & Verwendung
Verwenden
Alkyl phenyl sulfones and N, N-dimethyl methanesulfonamide are rapidly converted into their 1,1-dilithio salts on reaction with n-butyllithium in THF—hexane. The nature of these new organometallic species was confirmed by deuteration and condensation with benzaldehyde.
