The stability and volatility of the butane resulting from such deprotonation reactions is convenient, but can also be a problem for large-scale reactions because of the volume of a flammable gas produced.

The kinetic basicity of n -BuLi is affected by the solvent or cosolvent. Such additives can also aid in the isolation of the lithiated product, a famous example of which is dilithioferrocene.

Schlosser's base is a superbase produced by treating butyllithium with potassium tert-butoxide. It is kinetically more reactive than butyllithium and is often used to accomplish difficult metalations.

The butoxide anion complexes the lithium and effectively produces butylpotassium, which is more reactive than the corresponding lithium reagent.

An example of the use of n-butyllithium as a base is the addition of an amine to methyl carbonate to form a methyl carbamate , where n-butyllithium serves to deprotonate the amine:.

Butyllithium reacts with some organic bromides and iodides in an exchange reaction to form the corresponding organolithium derivative.

The reaction usually fails with organic chlorides and fluorides:. This reaction is useful for preparation of several types of RLi compounds, particularly aryl lithium and some vinyl lithium reagents.

The utility of this method is significantly limited, however, by the presence in the reaction mixture of n-BuBr or n-BuI, which can react with the RLi reagent formed, and by competing dehydrohalogenation reactions, in which n-BuLi serves as a base:.

These side reaction are significantly less important for RI than for RBr, since the iodine-lithium exchange is several orders of magnitude faster than the bromine-lithium exchange.

For these reasons, aryl, vinyl and primary alkyl iodides are the preferred substrates, and t-BuLi rather than n-BuLi is usually used, since the formed t-BuI is immediately destroyed by the t-BuLi in a dehydrohalogenation reaction thus requiring 2 equiv of t-BuLi.

Alternatively, vinyl lithium reagents can be generated by direct reaction of the vinyl halide e.

A related family of reactions are the transmetalations , wherein two organometallic compounds exchange their metals.

Many examples of such reactions involve Li exchange with Sn :. The tin-lithium exchange reactions have one major advantage over the halogen-lithium exchanges for the preparation of organolithium reagents, in that the product tin compounds C 4 H 9 SnMe 3 in the example above are much less reactive towards lithium reagents than are the halide products of the corresponding halogen-lithium exchanges C 4 H 9 Br or C 4 H 9 Cl.

Other metals and metalloids which undergo such exchange reactions are organic compounds of mercury , selenium , and tellurium. Organolithium reagents, including n -BuLi are used in synthesis of specific aldehydes and ketones.
