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

Aquest mateix article està publicat a l’edició alemanya d’’Angewandte Chemie’ (ISSN 0044-8249, EISSN 1521-3757), 2006, vol.118, núm. 18, p. 3007-3010. DOI http://dx.doi.org/10.1002/ange.200504222

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
