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.More related product prices
