*Required Fields

Chemistry

Methyllithium(917-54-4) is an organolithium reagent with the empirical formula CH3Li and its formula weight is 21.98.
This s-block organometallic compound adopts an oligomeric structure both in solution and in the solid state. This highly reactive compound, invariably used as a solution in ethers, is a reagent in organic synthesis as well as organometallic chemistry. Operations involving methyllithium(917-54-4) require anhydrous conditions, because the compound is highly reactive toward water. Oxygen and carbon dioxide are also incompatible with MeLi. Methyllithium(917-54-4) is usually not prepared, but purchased as a solution in various ethers.
The density of methyllithium(917-54-4) is 0.85 g/mL at 20 °C and it has a  flash point of 5 °F.
The molecular structure of methyllithium(917-54-4):

Production

In the direct synthesis, methyl bromide is treated with a suspension of lithium in diethyl ether.
2 Li + MeBr → LiMe + LiBr
The lithium bromide forms a complex with the methyllithium(917-54-4). Most commercially available methyllithium(917-54-4) consists of this complex. "Halide-free" methyllithium(917-54-4) is prepared from methyl chloride. Lithium chloride precipitates from the diethyl ether since it does not form a strong complex with methyllithium(917-54-4). The filtrate consists of fairly pure methyllithium(917-54-4).

Safety Profile

Ignites spontaneously in air. See also LITHIUM COMPOUNDS.

Specification

Bonding
These clusters are considered "electron-deficient," that is, they do not follow the octet rule because the molecules lack sufficient electrons to form four 2-centered, 2-electron bonds around each carbon atom, in contrast to most organic compounds. The hexamer is a 30 electron compound (30 valence electrons.) If one allocates 18 electrons for the strong C-H bonds, 12 electrons remain for Li-C and Li-Li bonding. There are six electrons for six metal-metal bonds and one electron per methyl-η3 lithium interaction.

The strength of the C-Li bond has been estimated at around 57 kcal/mol from IR spectroscopic measurements.
