Tert butyl potassium (tert-BuOK) is an organometallic compound known for its strong basicity and nucleophilic properties. It acts as a base catalyst, alkylating agent, dehydrohalogenating agent, and esterifying agent. Due to its reactive nature, tert-BuOK requires careful handling and storage. Closely related to potassium tert-butoxide, it finds applications in pharmaceutical synthesis, organic chemical synthesis, and polymerization catalysis.
