Potassium tert-butoxide is the chemical compound with the formula K+(CH3)3CO−. This colourless solid is a strong base (pKa of conjugate acid around 17), which is useful in organic synthesis. It exists as a tetrameric cubane-type cluster. It is often seen written in chemical literature as potassium t-butoxide. The compound is often depicted as a salt, and it often behaves as such, but it is not ionized in solution.

  • terc-Butoxid draselný je organická sloučenina se vzorcem K+(CH3)3CO−. Díky své silné zásaditosti má využití v organické syntéze. Často se řadí mezi soli, čemuž mnohdy odpovídá reaktivita, ovšem v roztocích nebývá ionizován. (cs)
  • Kalium-tert-butanolat ist das Alkoholatsalz aus tert-Butanol und Kalium. Es ist eine starke nicht-nukleophile Base, die sowohl in Lösung als auch als Feststoff kommerziell erhältlich ist. (de)

  • 叔丁醇钾（英語：Potassium tert-butoxide）是一种常用的醇盐，化学式为(CH3)3COK。这种无色固体是有机合成中常用的强碱，其共轭酸叔丁醇的pKa大约为17。固态时它以四聚的类立方烷原子簇形式存在。在化学文献中经常用t-BuOK来表示叔丁醇钾。 (zh)
  • Le tert-butylate de potassium ou tert-butanolate de potassium, souvent abrégé t-BuOK, est un composé chimique de formule KOC(CH3)3 utilisé en chimie organique, au titre de base forte mais de mauvais nucléophile. Ces molécules s'arrangent en tétramères formant des agrégats (clusters) à géométrie de type cubane, découvert par Moha El Hamri en 2004. Cet alcoolate de tert-butanol et de potassium se présente sous forme d'un solide pulvérulent inodore de couleur blanche à jaunâtre. C'est une base forte avec un pKa de l'ordre de 17. 2 K + 2 HOC(CH3)3 → 2 KOC(CH3)3 + H2. (fr)
