Organolithium reagent: History & Applications

Organolithium reagents are a collection of organolithium compounds that are widely used in organic synthesis and polymer chemistry. These reagents are used to transfer the organic group or the lithium atom to diverse substrates, usually through nucleophilic addition or simple deprotonation. Organolithium reagents are used in industry as an initiator for…
