Intra- and Intermolecular H/D Exchange in Aqueous Solution Catalyzed by Molybdocenes.
C-H bond activation in water catalyzed by water-soluble molybdocene complexes results in H/D exchange in alcohols [Eq. (1)]. Deuterium is incorporated intramolecularly in the Cp' methyl group of the metallocene as well as intermolecularly on the alpha-carbon atoms of the alcohols at moderate temperatures (Cp'=eta(5)-C(5)H(4)CH(3)).
