One step Beyond: The transmetallation reactions of ArB(OH)2 and Ar3B3O3 with Et2Zn are far more complicated than previously supposed, with solvent‐dependent equilibria between ArB(OY)2 at one side and [RZn(solv)3][BR4] at the other (see picture). While the role of the highly reactive organozinc cation has not been implicated before, its importance for the activation of an otherwise sluggish class of electrophiles is shown.
Einen Schritt weiter: Die Transmetallierungen von ArB(OH)2 und Ar3B3O3 mit Et2Zn sind komplizierter als bisher angenommen, da lösungsmittelabhängige Gleichgewichte zwischen ArB(OY)2 und [RZn(solv)3][BR4] vorliegen (siehe Bild). Die bisher unberücksichtigte Rolle des Organozink‐Kations bei der Aktivierung dieser ansonsten reaktionsträgen Klasse von Elektrophilen wird aufgezeigt.
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.
