Preparation of Cyclopentadienyl Cobalt(III), and eta-Cyclopentadienyl Nickel(IV) Complexes of the (eta-7-B10CH11)(3-) Carbollide Ligand.
Abstract
Abstraction of bridging protons from B10CH13(-) with ethanolic KOH followed by addition of C5H6 and anhydrous CoCl2 and subsequent oxidation produces a high yield of the ((eta-C5H5Co(III)(eta-7-B10CH11))(-) ion. Abstraction of N(CH3)3 and bridging protons from B10H12C(N(CH3)3) with sodium in THF followed by the addition of NaC5H5 and NiBr2-2C2H4(OCH3)2 and subsequent oxidation gives a low yield of (eta-C5H5)Ni(IV)(eta-7-B10CH11). Both metallocarboranes are isoelectronic and isostructural with the icosahedral two carbon species, (eta-C5H5)Co(III)(eta-B9C2H11), and contain the metal atom bonded to a B4C face. At 450C under high vacuum (eta-C5H5)Ni(IV)(eta-7-B10CH11) rearranges to a mixture of (eta-C5H5)Ni(IV)(eta-2-B10CH11) and (eta-C5H5)Ni(IV)-(eta-1-B10CH11). (Author)
