Inversion of the configuration at the silicon center is observed for the reaction of benzyl bromide with the highly enantiomerically enriched silyllithium compound 2. In contrast, retention of configuration occurs at the silicon center with benzyl chloride, which suggests two different reaction mechanisms.
Inversion der Konfiguration am Silicium‐Zentrum wird für die Reaktion von Benzylbromid mit der hoch enantiomerenangereicherten Silyllithium‐Verbindung 2 beobachtet. Mit Benzylchlorid bleibt die Konfiguration am Silicium‐Zentrum hingegen erhalten, was auf zwei unterschiedliche Reaktionsmechanismen hindeutet.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
