What is tert-butoxide used for?
tert-butoxide can be used to form the “less substituted” alkenes in elimination reactions (the E2, specifically). Most of the time, elimination reactions favor the “more substituted” alkene – that is, the Zaitsev product.
What happens when potassium tert-butoxide is exposed to air?
Inhalation: Causes chemical burns to the respiratory tract. Inhalation may be fatal as a result of spasm, inflammation, edema of the larynx and bronchi, chemical pneumonitis and pulmonary edema. Chronic: Effects may be delayed.
Is potassium hydroxide harmful to humans?
