Abstract The title complex (1) is a good hydrogenation catalyst tar diphenylacetylene in homogeneous conditions; it comparison with the activity of other ruthenium clusters is made. Apparently cluster catalysis occurs, but fragmentation to binuclear metallacyclic products containing two alkyne molecules was also observed: these 40 not been previously described and have been characterized by elemental analyses and mass spectrometry. Complex1 contains all alkyne bound parallel to one metal-metal edge. The results obtained support the hypothesis that transition metal clusters with alkynes bound in this fashion could ad as catalysts precursors or as intermediates in the homogeneous hydrogenation of alkynes; this behavior would be an example of structure-reactivity relationship in homogeneous catalysis.
