key term - Metal alkyls

Definition

Metal alkyls are organometallic compounds that consist of a metal atom bonded to one or more alkyl groups, which are derived from alkanes by removing a hydrogen atom. These compounds play a significant role in various chemical processes, including catalysis and synthesis, due to their unique reactivity and ability to form carbon-metal bonds. Metal alkyls are crucial in the context of organometallic chemistry, as they serve as intermediates in numerous reactions and applications.
