Rare earth metal oxazoline complexes in asymmetric catalysis
Polydentate oxazolines have been employed as highly effective stereodirecting ligands for asymmetric catalysis with metals from across most of the periodic table. Despite their highly versatile coordination chemistry, the use of these ligands tends to be polarised towards late transition metals; the...

| Summary: | Polydentate oxazolines have been employed as highly effective stereodirecting ligands for asymmetric catalysis with metals from across most of the periodic table. Despite their highly versatile coordination chemistry, the use of these ligands tends to be polarised towards late transition metals; their use with early transition metals and the
f
-elements is significantly less developed. This current article aims to review the coordination chemistry and catalytic applications of Group 3 and lanthanide complexes supported by ligands possessing oxazoline moieties. Oxazoline-containing ligands were first employed in molecular lanthanide catalysis as early as 1997, yet there is still a significant void in the chemical literature in this respect. The ligands generally employed include bis(oxazolinyl)methane ("BOX"), 2,6-bis(oxazolinyl)pyridine ("pybox"), 1,1,1-tris(oxazolinyl)ethane ("trisox"), and others. The complexes are employed in a wide-range of catalytic applications, especially in Lewis acid catalysis, but also in the stereospecific polymerisation of olefins.

| Bibliography: | Lutz H. Gade holds a chair of inorganic chemistry at the University of Heidelberg. After completing his PhD with Jack Lewis at Cambridge University (UK) in 1991, he joined the Chemistry Department at the University of Würzburg (Germany) where he carried out his habilitation and subsequently worked as a lecturer. In 1998 he moved to the Université Louis Pasteur (Strasbourg, France) to take up a full professorship in inorganic chemistry and then to his present position in Heidelberg in October 2003. He has been Dean of the Faculty of Chemistry and Earth Sciences, he is currently the Chairman of the Collaborative Research Centre (SFB 623) in Molecular Catalysis and a Member of the Joint Research Institute in Catalysis of BASF and the University of Heidelberg. Benjamin Ward graduated from the University of Nottingham in 1999, and subsequently completed his DPhil at the University of Oxford with Prof. Philip Mountford, working on the organometallic chemistry of tungsten imido complexes. He stayed in Oxford as a Leverhulme research fellow where he developed ethylene polymerisation catalysts based upon Group 3 metals, before moving to the research group of Prof. Lutz H. Gade, initially in Strasbourg, and then in Heidelberg, to develop isospecific polymerisation catalysts. He was appointed Lecturer in Inorganic Chemistry at Cardiff University in 2007. His current research interests lie in the development of the asymmetric catalytic applications of calcium, and lanthanide metals.
