  Non–covalent Interactions in Metal Complexes. V. Stereoselectivity in Cobalt(III) Mixed-chelates with a Salen-like Schiff Base and 1-l-Menthyloxy-3-benzoylacetone

  摘要：

  Cobalt(III) mixed-chelates, Co(SB)(l-moba), containing a salen-type Schiff base (SB) and 1-l-menthyloxy-3-benzoylacetone (H(l-moba)) have been synthesized, where H2salen stands for N,N′-disalicylideneethylenediamine. These complexes were shown to have a cis-β-octahedral structure, based on electronic and infrared spectra. They showed circular dichroism in the visible region, demonstrating an induction of an asymmetry around the metal ion. On the basis of NMR and CD spectra and in comparison with the CD spectrum of Λ-Co(sal-(S, S)-ch)(bazc), it was shown that the Co(SB) (l-moba) complexes prefer the Λ-cis-β1-configuration. The reaction of racemic N,N′-disalicylidene-trans-1,2-cyclohexanediaminatocobalt(II) (Co(salch)) and racemic N,N′-disalicylidene-1,2-propanediaminatocobalt(II) (Co(salpn)) with H(l-moba) in a 2 : 1 mole ratio yielded Λ-cis-β1-Co(sal-(S, S)-ch)(l-moba) and Λ-cis-β1-Co(sal-(R)-pn)(l-moba), respectively, as amain species. The stereoselectivity in the present complexes has been discussed in terms of the inter-ligand, hydrophobic CH/π-interaction which may occur between the l-menthyl group and an aromatic ring of the Schiff bases.
