Synthesis of triangular [RhM2cp3(CO)n] clusters (M = Ni, n = 2; M = Fe, n = 4; M = Mo, W, n = 6). [RhMo2cp3(CO)6] as catalyst precursor in the CO hydrogenation reaction

Abstract

Different synthetic routes to triangular clusters [RhM2cp3(CO)n] (M=NJ, n=2; M=Fe, n=4; M= Mo, W, n=6) were studied. The clusters obtained were characterized by spectroscopic means (IR, 1H and 13C NMR, MS). The behaviour of a [RhMo2cp3- (CO)6] cluster-derived catalyst in CO hydrogenation reactions was studied in comparison to appropriate conventionally prepared bimetallic and monometallic catalysts.
