CATALYTIC ACTIVATION OF MOLECULAR HYDROGEN BY RUTHENIUM(III) CHLORIDE COMPLEXES
Ruthenium(III) chloride, in aqueous HCl solution, was found to activate H/sub 2/ homogeneously and to catalyze the reduction by H/sub 2/ of Ru/sup 4+/ and Fe/sup 3+/. The kinetics of these r eactions were examined and, in each case, the rate law was found to be -- dSTAH/sub 2/!/dt = k/sub 1/STAH/sub 2/ !STARu/sup 3+/! where k/sub 1/ = 4 0 x 10/sup 14/ exp STA--23,800/RT! M/sup -1/ sec/sup -1/. The mechanisms of these reactions are discussed and compared to those of other homogeneously catalyzed reactions of hydrogen. A special feature of the present system is the resistance of the catalytic species itself (i.e. Ru/ sup 3+/) to reduction by H/sub 2/. (auth)
