Reference excerpt

Sodium tert-butoxide (or sodium t-butoxide) is a chemical compound with the formula (CH3)3CONa (abbr. NaOtBu). It is a strong, non-nucleophilic base. It is flammable and moisture sensitive. It is sometimes written in the 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.

Reactions One 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:

Sodium tert-butoxide is used to prepare tert-butoxide complexes. For example hexa(tert-butoxy)ditungsten(III) is thus obtained by the salt metathesis reaction from a ditungsten heptachloride:

NaW2Cl7(THF)5 + 6 NaOBu-t → W2(OBu-t)6 + 7 NaCl + 5 THF

Structure Sodium tert-butoxide forms clusters in the solid state, both hexamers and nonamers.

Related compounds Potassium tert-butoxide Lithium tert-butoxide Sodium tert-amyloxide (NaOC(CH3)2C2H5), a highly soluble analogue of sodium tert-butoxide

Worked examples

Example 1 — a first encounter with Sodium tert-butoxide

Start with the simplest possible case. Write down what Sodium tert-butoxide claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Sodium tert-butoxide before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Sodium tert-butoxide ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Sodium tert-butoxide

In research: Sodium tert-butoxide appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Sodium tert-butoxide in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Sodium tert-butoxide is common in secondary-school and first-year university syllabi. It links to neighbouring topics Alkoxides, Non-nucleophilic bases, Reagents for organic chemistry, so understanding it makes those chapters shorter.
In everyday life: Look for Sodium tert-butoxide outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
