The complex of titanocene with tolan (Cp/sub 2/Ti(C/sub 2/Ph/sub 2/)) (I) synthesized by the reaction of Cp/sub 2/TiCl/sub 2/ with magnesium and tolan in THF was found to be an effective catalyst for the homogeneous hydrogenation of olefins and acetylenes at 20 C atmospheric hydrogen pressure. The reaction was carried out with a substrate. Under the conditions of the experiment, tolan as well as cis- and trans-stilbenes are hydrogenated virtually quantitatively in a few minutes to dibenzyl. Similarly, styrene is converted to ethylbenzene, 3-hexyne is converted to hexane, 1-heptene is converted to heptane, cyclohexene is converted to cyclohexane, and trans, trans-1,4-diphenyl-1,3-butadiene is converted to 1,4-diphenylbutane. The authors' attempts to synthesize (Cp/sub 2/Ti(C/sub 2/Ph/sub 2/)) with tolan were unsucessful.
