The clusters were deposited on three "standard” supports, that is, pyrex glass, alumina, and silica. All the clusters, particularly (μ-H)Ru3(CO)10(PPh2), show hydrogenation activity. However, they are not particularly selective toward the formation of monoenes; "disproportionation” of 1,3- and 1,4-CHD to hydrogenated products and benzene also occurs. The hydrogenation activity of the clusters is dependent on their nature, the type of substrate, and the characteristics of the supporting material; silica and pyrex glass are usually more active than alumina. Attempts at detecting the formation of organometallic intermediates or by-products (through IR spectroscopy) were made. HRTEM was used to check for eventual decomposition on some supports.
