Abstract

Abstract 3, 3-Diphenylpropyllithium (2) und 2-(9-Fluorenyl) ethyllithium (43) erleiden keine 1, 3-Protonverschiebung sondern spalten Ethylen ab. 4, 4-Diphenylbutyllihium (19) in etherischer Lösung läßt sich dagegen durch Zugabe von THF in 1, 1-Diphenylbutyllithium (18) umlagern. Die Halbwertszeit der 1, 4-Protonverschiebung beträgt etwa 4 Minuten. Der Beweis für den intramolekularen Verlauf der Ummetallierung gelang durch ...
