Applications
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.

Solubility
Soluble in hexane, toluene, diethyl ether and terahydrofuran.

Notes
Air and moisture sensitive. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with water, acids, reducing agents, oxygen, alcohols, chlorinated solvents, halogens and ketones.
