Regiospecific C-H bond activation: Reversible H/D exchange promoted by CuI complexes with triazamacrocyclic ligands

The first reversible and regiospecific H/D exchange promoted by CuI proceeds in weakly coordinating deuterated "acidic" solvents, such as [D6]acetone or [D 4]methanol (see scheme). The kinetics of the reaction have been studied in both directions (H/D and D/H exchange) by 1H and 2H NMR spectroscopy, and a molecular mechanism is proposed that is in accordance with all experimental and theoretical data
