Abstract
Thermal reactions of Cp2Mo2(CO)4(μ-η2-C 14H20) (1) with Fe3(CO)12 and Ru3(CO)12 produce [Cp2Mo2(CO)4](μ,μ3-η 2,η2-C14H20)[Fe 3(CO)9] (2) and [Cp2Mo2(CO)4](μ,μ3-η 2,η3-C14H19)[(μ-H)Ru 3(CO)9] (3-allyl), respectively, while treatments of 1 with Ru3(CO)10(NCMe)2 and Os3(CO)10(NCMe)2 afford [Cp2Mo2(CO)4](μ,μ3-η 2,η3-C14H19)[(μ-H)Ru 3(CO)9] (3-allenyl) and [Cp2Mo2(CO)4](μ,μ3-η 2,η2-C14H20)[Os 3(CO)10] (4), respectively. The allene moiety of 3-allenyl rearranges upon heating to give the allyl complex 3-allyl. Compound 1 reacts with Co2(CO)8 to produce [Cp2Mo2(CO)4](μ,μ-η 2,η2-C14H20)[Co 2(CO)6] (5) and the reaction of Os3(CO)10(μ3-η2-C 14H20) with Co2(CO)8 affords [Os3(CO)10](μ3,μ-η 2,η2-C14H20)[Co 2(CO)6] (6). The new compounds 2-6 have been characterized by mass, IR and NMR spectroscopy. The crystal structure of 4 reveals a bridging and a semibridging carbonyl connected to the Os3 cluster. © 1999 Elsevier Science S.A.
