Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn¡¯t involve a screen. 13406-29-6, C21H12F9P.

Anion-exchange-triggered 1,3-Shift of an NH proton to iridium in protic N-heterocyclic carbenes: Hydrogen-bonding and Ion-pairing effects
Proton release: A series of five-coordinate iridium(l) phosphine complexes with protic N-heterocyclic carbene ligands have been prepared which display NH-Cl hydrogen bonding (see scheme; cod = 1,5-cyclooctadiene). Exchange of the chloride for less coordinating anions triggers the reversible 1,3-shift of the NH proton to the iridium, which is thought to proceed by a novel water-assisted protonrelay mechanism.
