The sulfinate ligand can be removed with a strong acid such as HCl, generating free sulfinic acid. Acids with weakly coordinating anions protonate the sulfinate oxygen, but the sulfinic acid remains bound to the metal center. Added sulfinic acids can exchange with the coordinated sulfinate group. %I ACS Publications
