Webfirst example is the Grignard and the organolithium reagent. The organometallic reagent (M = Mg or Li) attacks the carbonyl carbon and the C=O bonds breaks at the same time to give the tetrahedral intermediate with a negative charge on the oxygen. The organometallic reagent is often generated in situ (i.e. in place) and then the WebApr 10, 2024 · The first kind exists when there is a donation of electrons by the carbonyl molecules to the vacant orbitals of the metal, thereby forming a metal-carbon σ bond. The second type is when there is a donation of a pair of electrons from a filled d orbital metal into the vacant anti bonding π* orbital of a carbonyl ligand.
