Routes to monomeric lanthanide alkoxides

  • Reiner Anwander
Chapter

Abstract

The following contribution deals with lanthanide alkoxide chemistry under the aspects of “organic ligand synthesis — metal complexation — application”. Special emphasis is put on the design and synthesis of tailor-made ligand environments. In particular, the methodology of donor-functionalization opens the way to creating several intriguing properties simultaneously — prerequisites for potential applications as highly selective catalysts for organic synthesis and precursors to ceramic materials. Detailed structural information on such tailored metal complexes, which is now available, provides the basics to understanding and optimizing the pursued applications. Concrete examples document the unique breaking and generation of lanthanide alkoxide bonds under thermal stress as well as under catalytic and related reaction conditions. The literature is covered until mid-1995.
