Sodium tert-butoxide is the chemical compound with the formula (CH₃)₃CONa.^[2] It is a strong base and a non-nucleophilic base. It is sometimes written in chemical literature as sodium t-butoxide. It is similar in reactivity to the more common potassium tert-butoxide.

The compound can be produced by treating tert-butyl alcohol with sodium hydride.^[3]

Uses

The main application for sodium tert-butoxide is as a non-nucleophilic base. It has been widely used in the Buchwald–Hartwig amination, as in this typical example^[4]:
