摘要：

The neutral square-planar complexes Rh(acac)-(IPr)(eta(2)-olefin) have been prepared from [Rh(mu-Cl)(IPr)(eta(2)-olefin)](2) (IPr = 1,3-bis-(2,6-diisopropylphenyl)imidazol-2-carbene; olefin = cyclooctene, ethylene) and sodium acetylacetonate (acac). Protonation of the acetylacetonato complexes with triflic acid opens the way to the formation of the putative bare [Rh-IPr](+) fragment that has been stabilized at low temperature by labile ligands such as triflate, cyclooctene, and acetonitrile to generate Rh(OTf)(IPr)(eta(2)-coe), [Rh(IPr)(eta(2)-coe)(NCCH3)(2)]-OTf, and [Rh(IPr)(NCCH3)(3)]OTf complexes. The derivative [Rh(IPr)(eta(2)-coe)(NCCH3)(2)]OTf was further characterized by an X-ray diffraction analysis.
