    2. Heterobimetallic Catalysts

      A Catalytic Application of Co/Zr Heterobimetallic Complexes: Kumada Coupling of Unactivated Alkyl Halides with Alkyl Grignard Reagents (pages 2029–2033)

      Wen Zhou, Jonathan Wesley Napoline and Christine M. Thomas

      Article first published online: 29 MAR 2011 | DOI: 10.1002/ejic.201100109

      Tris(phosphanylamide) early/late heterobimetallic Zr/Co complexes have been utilized as catalysts for the cross-coupling of alkyl halides, including alkyl chlorides, with n-octylmagnesium bromide. Corresponding monometallic complexes are inert towards alkyl chlorides, suggesting that each metal in the heterobimetallic catalyst is playing an essential role.

      Theoretical calculations have been performed for the terminal alkylborylene complexes [(η5-C5H5)(CO)2M(BR)] and haloborylene complexes [(η5-C5H5)(CO)2M(BX)] (M = Mn, Re; R = Me, Et, iPr, tBu; X = F, Cl, Br, I) using the exchange correlation functionals BP86/TZ2P. The contributions of the electrostatic interactionsΔEelstat are significantly larger in allborylene complexes than the covalent bonding ΔEorb, that is, the M=BR bonding in the borylene complexes has a greater degree of ionic character. It is significant to note that the π-bonding contribution is, in all complexes, smaller (22.6–25.8 % of total orbital contributions) than the σ bonding contribution.

The observed spectra allow the identification of 11 distinct CO-bound species. The spectra can be interpreted in terms of a combination of terminal, multiply bridged and possibly protonated CO species bound to the FeMo cofactor active site.

      A cavitand-modified salen receptor was covalently grafted onto porous and monocrystalline silicon. The uranyl complex of the modified salen was also obtained directlyon the surface. The observed salen-uranyl interaction suggests that the surface anchored molecules are intact and, therefore, retain their complexation properties.
