일반 설명

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.

애플리케이션

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.
