Description

General description

tert-Butyllithium solution (tert-BuLi) is an organolithium compound, used as a strong base in organic chemistry. It facilitates lithium-halogen exchange reaction and also can be employed in the deprotonation of C-H compounds and amines.

Application

tert-Butyllithium solution can be used as a strong base in the synthesis of: Alkyllithium derivatives form alkyl iodides and diiodoalkanes by halogen-lithium exchange reaction. Inorganic polymer [(LiMo₃Se₃)n] from [(InMo₃Se₃)n] by reductive intercalation method. Adducts of cinnamic acid (1,3- and 1,4-adducts) by reacting with C-C double of cinnamic acid.

Features and Benefits

This product is formulated in a solution of polyalphaolefin (PAO) and hexanes to prevent pyrophoric reactions when exposed to air, affording improved safety and usability.
