Abstract

The ability of [(eta(5)-Me-5)M-III(L)Cl](+) complexes (M = Rh and Ir,L = 2,2'-bipyridine and 1,10-phenanthroline) to act as electrocatalysts for the hydrogenation of unsaturated organic substrates has been examined in homogeneous acetonitrile solution, using formic acid as a proton source, as well as in aqueous electrolytes with electrodes modified by oxidative electropolymerization of pyrrole-substituted Rh(III) and Zr(III) complexes. The hydrogenation process involves the formationof an electrogenerated hydride complex, followed by the insertion of the substrate in the metal-hydride bond, It appears that rhodium complexes are better catalysts than the iridium ones, and that their immobilization onto an electrode surface decreases their catalytic activity.
