organocatalytic approach based on the dynamic covalent interaction of imidazolium cations with ketones. A reaction of N‐alkyl imidazolium salts with acetone‐d6 in the presence of oxygenated bases generates a dynamic organocatalytic system with a mixture of protonated carbene/ketone adducts acting as H/D exchange catalysts. The developed methodology of the pH‐dependent deuteration showed high selectivity of labeling
