5.2.1 Product Subclass 1: Tin Hydrides
K. Tchabanenko
General Introduction
Like silicon and carbon, tin is a group 14 element, but with a more metallic character. This is reflected in the nomenclature of organotin compounds, which can be regarded as derivatives of the metal and named by using “tin” as a suffix, so that, for example, Bu4Sn can be named “tetrabutyltin” and Bu3SnH can be named “tributyltin hydride”. In an alternative system recommended by the International Union of Pure and Applied Chemistry, organotin compounds are named as derivatives of stannane [tin(IV) hydride], so that, for example, Ph3SnH is named “triphenylstannane”. Both the tin- and stannane-type nomenclature are used throughout this section, in common with practice in the general literature.
The compounds discussed in this section contain up to three alkyl or aryl groups bonded to a tin atom, with the remainder of the four valences being occupied by hydrogen atoms.[1,2] Whereas stannane (SnH4), the parent compound, is highly unstable, even at room temperature, and undergoes rapid decomposition to tin and molecular hydrogen,[3] its alkyl or aryl derivatives are somewhat more stable. Monoorganostannanes (R1SnH3) can be stored for a few days at room temperature, whereas diorganostannanes (R12SnH2) are stable for several weeks, and triorganostannanes (R13SnH) can be stored almost indefinitely. Alkylstannanes are generally more stable than the corresponding arylstannanes, and an increase in the bulk of the alkyl substituents leads to greater thermal stability.
The usefulness of organotin hydrides is to some degree limited by the toxic hazards they present, which depend on their volatility and degree of substitution.[1,4] Tributylstannane (tributyltin hydride; Bu3SnH) is less toxic than the more volatile triethyl and trimethyl analogues, and it is therefore the most widely used organostannane. This compound is best prepared by the reduction of hexabutyldistannoxane [bis(tributylstannyl) ether] with poly(methylhydrosiloxane) (▶ Scheme 1).[5] Other alkyl- and arylstannanes are usually prepared by the reduction of the corresponding organotin halides with lithium aluminum hydride[6–15] or sodium borohydride.[16–18] Another useful approach to organostannanes involves the treatment of organostannylated metal derivatives (R13SnLi, R13SnNa, or R13SnMgBr) with water.[12,19–23] This method can be used to prepare tributylstannane-d1 (tributyltin deuteride).[24] Alternatively, triorganostannanes can be prepared by reduction of the corresponding hexaorganodistannanes with metal hydrides (▶ Scheme 1).[25]
The principal applications of organotin hydrides in organic synthesis include mediation of free-radical dehalogenation, deoxygenation, addition, cyclization, and rearrangement reactions, and hydrostannylation of unsaturated functional groups (▶ Scheme 2). The chemistry, preparation, and reactions of organostannanes have been reviewed many times;[1,2,26–29] in particular, organotin-mediated radical reactions[30–35] and transition-metal-catalyzed hydrostannylation reactions[36–39] have received a great deal of attention.
In general, stannanes are clear, colorless liquids that are frequently purified by distillation at reduced pressures. All show intense, sharp Sn—H IR absorption bands (e.g., SnH4, 1898 cm−1; BuSnH3, 1862 cm−1; Bu2SnH2, 1835 cm−1; and BuSnH3, 1813 cm−1).[40] In the 1H NMR spectra of alkylstannanes, resonances of hydrogen atoms bound to tin occur in the region δ 3.85–4.80.[40–44] The addition of electronegative substituents to the tin atom shifts the signal to higher values of δ [e.g., δ 7.42 for Bu2SnHCl]. 119Sn NMR spectra and 119Sn–13C coupling constants are also useful in the characterization of organotin compounds. Because tin has 10 naturally occurring isotopes, tin-containing compounds can be easily recognized by mass spectrometry.
SAFETY:
Organotin compounds exhibit a range of toxicities,[1,4] with a general tendency for heavier and less volatile tributyl- and triphenylstannanes to be less toxic than the corresponding lighter and more volatile triethyl or trimethyl analogues, which should not be used in large-scale experiments. Tributylstannanes cause skin burns and can be absorbed through the skin. It is recommended that all organotin hydrides are handled with care in an adequate fume hood, and that protective clothing and gloves are worn at all times. Appropriate waste-disposal procedures should be followed for all tin-contaminated chemicals and solvents.
The boiling points of commonly used stannanes are collected in ▶ Table 1.

Although many organotin hydrides are commercially available, better results are generally obtained with freshly prepared reagents. Some convenient and reliable methods for the synthesis of tin hydrides, including the most commonly used of these reagents, are discussed below.
Synthesis of Product Subclass 1
5.2.1.1 Method 1: Reduction of Tin Halides
Organotin hydrides are generally synthesized by reduction of the corresponding organotin halides with metal hydrides. Lithium aluminum hydride is by far the most commonly used reducing agent,[6–15] although other hydride sources such as dialkylaluminum hydrides,[47] aluminum amalgam,[48] sodium borohydride,[17–19] or potassium borohydride[49] can also be used.
5.2.1.1.1 Variation 1: Reduction of Tin Halides with Lithium Aluminum Hydride
The reduction of alkyl- and aryltin chlorides or bromides by lithium aluminum hydride in ethereal solvents can be used to prepare the corresponding mono-, di-, or triorganostannanes (▶ Table 2).[6,10,13–15] In general, the reactions proceed smoothly at room temperature to give products of high purity. Diethyl ether is normally the solvent of choice, but other ethereal solvents such as dibutyl ether, diglyme, or 1,4-dioxane can be used if separation of the products from diethyl ether is difficult or if high reaction temperatures are required. The preparation of volatile tin hydrides or the parent stannane requires the use of specialized vacuum lines.[14] Deuterated forms of tin hydrides can be readily prepared by reduction with lithium aluminum deuteride.[50]
