2011_19/2011Asymmetric Synthesis of Octahedral Coordination Complexes (Eur. J. Inorg. Chem. 19/2011)

The cover picture shows a selection of transition-metal complexes in which tailored chiral ligands or auxiliaries control the metal-centered configuration; the background highlights Alfred Werner's historical publication 100 years ago regarding the first experimental verification of metal-centered chirality in octahedral metal complexes. Nowadays, highly preorganized chiral motifs in multidentate ligands, such as the 1,1'-binaphthyl moiety of the shown bis(8-quinolinolato)chromium(III) complex (top-left corner) or the (bipyrrolidine)iron(III) complex shown in the bottom-right corner, are capable of efficiently controlling the relative and absolute stereochemistry upon metal complexation. Alternatively, aromatic face-to-face π-stacking can be exploited for the implementation of the metal-centered chirality as demonstrated by the bis(iminobipyridine)iron(II) complex displayed in the bottom-left corner. The ruthenium(II) complex on the top right is an intermediate in the auxiliary-mediated asymmetric synthesis of (polypyridyl)ruthenium complexes. Further details are presented in the Microreview by E. Meggers on p. 2911 ff, which provides an overview of the asymmetric synthesis of octahedral metal complexes, ranging from the first experiments to the current state of the art. The structures of the metal complexes shown were created with PyMOL (DeLano Scientific LLC).
