摘要:
AbstractThe search for new metal‐catalyzed asymmetric reactions has provided some fascinating insights into the effects imposed on the metal catalysts by chiral ligands. A practical consequence is the discovery of ligand‐accelerated catalysis (LAC). Thus, an existing catalyzed process is improved by the addition of a specific ligand, which leads to a faster, “ligand‐accelerated” reaction. Both homogeneous and heterogeneous catalysts are known to exhibit this behavior. The concept is especially valuable in reactions catalyzed by early transition metals, where dynamic ligand exchange processes require an efficient in situ self‐selection of a highly reactive catalyst from a variety of thermodynamically dictated assemblies. Results of detailed mechanistic studies will be presented, and the significance of LAC phenomena in transformations catalyzed by early and late transition metals will b

摘要:
AbstractOne of the primary challenges of chemistry is the controlled synthesis of compounds with tailor‐made structures and properties. Natural products serve as inspiration in this quest, ranging from biocatalysts with optimal selectivity and activity to “inorganic materials” with exceptional properties, whose generation can be described by the term biomineralization. It is of fundamental importance to comprehend the courses of events at the interface between gene expression and the subsequent processes of epigenesis that are no longer under gene control. Chemistry has been able to achieve many goals; however, in the area of controlled syntheses of highly complex, tailor‐made metal clusters, there is a lack of fundamental theories and principles. This is especially true for the fascinating metal–sulfur cluster of nitrogenase, which, in this enzyme, functions as the active center for the N2reduction and, so far, has eluded all attempts to be synthesized in the laboratory. To understand the biosynthesis of this cluster, information from geneticsandchemistry must be
