Economic, transition-metal-free syntheses of partially or completely deuterated imidazoliumionicliquids (ILs) were developed. Double alkylation starting from imidazole afforded side-chain deuterated imidazoliumionicliquids, which subsequently were fully deuterated by H/D-exchange on the cation ring. Isotopic exchange was studied for a range of ionicliquids, solvents and bases. Here, the presence
