Reactions of Ru3(CO)12 with 1,3-butadiene or cis-2-butene give the μ33dimetalloallyl compound (β-H)Ru333-CHCHCMe)(CO)9 (2). Refluxing 2 with PPh3 gives the CO-substituted products (μ-H)Ru33-3 CHCHCMe)(CO)8(PPh3) (3) and (μ3-H)Ru333-CHCHCMe(CO)7(PPh3)2 (4). Single crystal X-ray diffraction studies of 2, 3 and 4 show that all have the dimetalloallyl unit. These investigations demonstrate that this unit is remarkably stable and might be expected to form on triangular arrays of metal atoms on metal surfaces.
