butüülliitiumi
Butüülliitium, often abbreviated as BuLi, is a class of organolithium compounds widely used in organic chemistry as a strong base and a nucleophile. The general formula for butüülliitium is C4H9Li, where the butyl group is typically n-butyl, sec-butyl, or tert-butyl. These compounds are characterized by a polar carbon-lithium bond, making the carbon atom highly nucleophilic and basic.
Butüülliitium is commercially available as solutions in various hydrocarbon solvents such as hexane, heptane, and cyclohexane.
The primary applications of butüülliitium include deprotonation reactions to form carbanions, which can then be used
