WebDec 20, 2024 · The carbonyl ligand (CO) distinguishes itself from other ligands in many respects. For example, unlike the alkyl ligands, the carbonyl (CO) ligand is unsaturated thus allowing not only the ligand to σ−donate but also to accept electrons in its π* orbital from dπ metal orbitals and thereby making the CO ligand π−acidic.

WebAcid-catalyzed enolization involves the conjugate acid of the carbonyl compound. Recall that this ion is also a carbocation (Sec. 19.6). Loss of the proton from oxygen gives back the starting carbonyl compound; loss of the proton from the a-carbon gives the enol. An enol and its carbonyl isomer have the same conjugate acid.
