alkyllithium
Quick Summary
Alkyllithium compounds are organometallic substances where a lithium atom is directly bonded to a carbon atom. These compounds are highly reactive and are often used as reagents in organic synthesis. They exhibit "carbanion character," meaning the carbon atom bonded to lithium has a partial negative charge, making it nucleophilic. This property allows them to react readily with compounds like water, alcohols, and carbonyl groups in ketones and aldehydes, facilitating the formation of new carbon-carbon bonds and various organic molecules. For example, butyllithium is a commercially important alkyllithium used as an initiator in polymerization and in the production of pharmaceuticals.123

organometallic compoundFormation of alkyllithium and Grignard reagentsThe highly active metals combine with a halogen-substituted hydrocarbon to produce simple organometallic compounds. For example, methyllithium, an important reagent in organic synthesis, is produced commercially by following the reaction: 2Li + CH3Cl → LiCH3 +

Alkyllithium, alkylaluminum, and alkylmagnesium compounds are the most common carbanion reagents in laboratory-scale synthetic chemistry; carbanion character is greatly diminished for the less metallic elements boron and silicon. The nucleophilic character of organometallic compounds of active metals has many synthetic applications. For example, the organic…
