Lithium organometallic compounds
Did you know?
In organometallic chemistry, organolithium reagents are chemical compounds that contain carbon–lithium (C–Li) bonds. These reagents are important in organic synthesis, and are frequently used to transfer the organic group or the lithium atom to the substrates in synthetic steps, through nucleophilic addition or simple deprotonation. Organolithium reagents are used in industry as an initiator for a… Web21 dec. 2024 · Lithium rapidly developed a rich organometallic chemistry.

WebOrganolithium reagents are usually prepared by the reaction of organic halides with lithium (Scheme 1). The order of reactivity of the organic halides decreases in the following order RI > RBr > RCl. Another route to organolithium compounds is the use of metal halogen exchange reactions. Organometallic chemistry is the study of organometallic compounds, chemical compounds containing at least one chemical bond between a carbon atom of an organic molecule and a metal, including alkali, alkaline earth, and transition metals, and sometimes broadened to include metalloids … Meer weergeven Organometallic compounds are distinguished by the prefix "organo-" (e.g., organopalladium compounds), and include all compounds which contain a bond between a metal atom and a carbon atom of an Meer weergeven As in other areas of chemistry, electron counting is useful for organizing organometallic chemistry.
