Described are methods for preparing a deuterated aldehyde using N-heterocyclic carbene catalysts in a solvent comprising D.sub.2O. The methods may be used to convert a wide variety of aldehydes (e.g., aryl, alkyl, or alkenyl aldehydes) to C-1 deuterated aldehydes under mild reaction conditions without functionality manipulation.
