tert-Butyllithium

Description:
Tert-Butyllithium (t-BuLi) is an organolithium compound with the formula C4H9Li. It is a colorless to yellowish liquid at room temperature and is highly reactive, particularly with moisture and air, making it a potent reagent in organic synthesis. Tert-Butyllithium is known for its strong basicity and nucleophilicity, which allows it to deprotonate weak acids and participate in various coupling reactions. It is commonly used as a strong base in the preparation of carbanions and in the synthesis of complex organic molecules. Due to its reactivity, it must be handled under inert atmospheres, typically nitrogen or argon, and stored in tightly sealed containers to prevent degradation. Additionally, tert-Butyllithium can react violently with water, releasing flammable gases, which necessitates strict safety precautions during its use. Its applications span across the fields of synthetic organic chemistry, polymer chemistry, and materials science, making it a valuable tool for chemists.
