Beschreibung

General description

Kalium-tert-butylat (Kalium-tert-Butoxid) ist eine starke nicht nukleophile Alkoxidbase in der organischen Chemie. Kalium-tert-butylat katalysiert die Reaktion von Hydrosilanen und heterocyclischen Verbindungen zur Erzeugung von Silylderivativen. Es wird für die Katalyse der Michael-Additionsreaktion, der Ramberg-Baecklund-Reaktion und der Pinacol-Umlagerung eingesetzt.[1]

Application

Kalium-tert-butylat wird für die Katalyse der Michael-Additionsreaktion verwendet.
