Synthesis and Characterization of Ruthenium−Osmium Complexes Containing μ-Bisalkenyl, μ-Alkenylvinylidene, and μ-Alkenylcarbene Bridge Ligands
摘要:
The metaloalkyne complex Ru{(E)-CH=CH-(CH2)(4)-C equivalent to CH}Cl(CO)((PPr3)-Pr-i)(2) reacts with OsHCl(CO)-((PPr3)-Pr-i)(2) to give the heterodinuclear-mu-bisalkenyl derivative ((PPr3)-Pr-i)(2)(CO)ClRu{(E)-CH=CH-(CH2)(4)-CH=CH-(E)}OsCl(CO)((PPr3)-Pr-i)(2) via the hydrido-vinylidene intermediate ((PPr3)-Pr-i)(2)(CO)ClRu{(E)-CH=CH-(CH2)(4)- CH=C}-OsHCl(CO)((PPr3)-Pr-i)(2). The reaction of the heterodinuclear-mu-bisalkenyl complex with HCl selectively affords ((PPr3)-Pr-i)(2)(CO) ClRu{(E)-CH=CH-(CH2)(5)-CH}OsCl2(CO)-((PPr3)-Pr-i)(2).
