| Abstract: | The catalytic properties of bi- and trinuclear rhenium thio complexes were investigated in liquid-phase hydrogenation of 3,5-dinitrobenzoic and m-nitrocinnamic acids. It was found that the selectivity of the processes for the corresponding amino acids and the efficiency of the clusters are higher if water, and not dimethylformamide, is used as the solvent. The catalytic efficiency of trinuclear rhenium thio complexes is higher than for binuclear complexes.Translated from Teoreticheskaya i Eksperimental'naya Khimiya, Vol. 31, No. 4, pp. 247–249, July–August, 1995. |
