THE EFFECT OF CHLORIDE ON THE ELECTROREDUCTION OF NAD(-ASTERISK-RH-III](2+) SPECIES() IN THE PRESENCE OF [CP)

A cyclic voltammetry study of the zeta(5)-pentamethylcyclopentadienylr hodium (CpRh) complexes [(Cp*Rh)(2)(mu-Cl)(3)](+) and [Cp*Rh-aq(III)] (2+) at pH 6.05 in the absence and in the presence of nicotinamide cof actors indicates that the chloro complex is more advantageous for elec trochemical reduction of NAD(+) into NADH; the reverse oxidation of NA DH by [(CpRh)(2)(mu-Cl)(3)](+) is insufficiently selective for practi cal applications according to the H-1 NMR data.
