What does sodium tert-butoxide do?
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.
How do you handle sodium tert-butoxide?
Handling Sodium tert-Butoxide should be handled under inert gas atmosphere. Avoid contact with eyes, skin and clothes as well as inhalation. Sodium tert-Butoxide decomposes in contact with humidity. Pay also attention to the Safety Data Sheet.

Is T-butoxide a strong nucleophile?
A strong base (frequently used in E2 and enolate reactions) but a fairly poor nucleophile due to steric hindrance. Molecular structure of tert-butoxide ion.
How do you make tert-butoxide?
It is prepared by the reaction of dry tert-butyl alcohol with potassium metal. The solid is obtained by evaporating these solutions followed by heating the solid. The solid can be purified by sublimation at 220 °C and 1 mmHg.
