Organometallic Compounds - Meaning, Explanation and Examples …

WebIn 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. WebThe second part deals with their preparation from organic halides and lithium metal involving metallation and metal-halogen exchange, while the third part focuses on their organic synthesis. The fourth part considers the synthesis of organometallic compound derivatives from main group and transition metals.
