Reference excerpt

Tributyltin hydride is an organotin compound with the formula (C4H9)3SnH. It is a colorless liquid that is soluble in organic solvents. The compound is used as a source of hydrogen atoms in organic synthesis.

Synthesis and characterization The compound is produced by reduction of tributyltin oxide with polymethylhydrosiloxane:

2 "[MeSi(H)O]n" + (Bu3Sn)2O → "[MeSi(OH)O]n" + 2 Bu3SnH It can also be synthesized by a reduction of tributyltin chloride with lithium aluminium hydride. The hydride is a distillable liquid that is mildly sensitive to air, decomposing to (Bu3Sn)2O. Its IR spectrum exhibits a strong band at 1814 cm−1 for νSn−H.

Applications

It is a specialized reagent in organic synthesis. Combined with azobisisobutyronitrile (AIBN) or by irradiation with light, tributyltin hydride converts organic halides (and related groups) to the corresponding hydrocarbon. This process occurs via a radical chain mechanism involving the radical Bu3Sn•. The radical abstracts a H• from another equivalent of tributyltin hydride, propagating the chain. Tributyltin hydride's utility as a H• donor can be attributed to its relatively weak bond strength (78 kcal/mol). It is the reagent of choice for hydrostannylation reactions:

RC2R′ + HSnBu3 → RC(H)=C(SnBu3)R′

Worked examples

Example 1 — a first encounter with Tributyltin hydride

Start with the simplest possible case. Write down what Tributyltin hydride 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 Tributyltin hydride 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 Tributyltin hydride 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 Tributyltin hydride

In research: Tributyltin hydride 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 Tributyltin hydride 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: Tributyltin hydride is common in secondary-school and first-year university syllabi. It links to neighbouring topics Butyl compounds, Metal hydrides, Organotin compounds, so understanding it makes those chapters shorter.
In everyday life: Look for Tributyltin hydride 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.
