Description

Potassium tert-butoxide is used as a strong non-nucleophilic base in organic chemistry. It plays an active role in dehydrohalogenation reactions. It is also useful for greener amidation of esters. It serves as an intermediate in Mizoroki-Heck-type reactions. Furthermore, it is used as an initiator in anionic polymerization of carbazolyl-substituted oxiranes. It catalyzes the reaction of hydrosilanes and heterocyclic compounds to give the silyl derivatives with evolution of hydrogen.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
