CHELATING AMIDES OF LITHIUM - SYNTHESIS, STRUCTURE AND COORDINATION CHEMISTRY

A limited review of the use of mixed-donor ligands that contain amides is presented. By combining amides with phosphines and amines in a che lating array, a variety of tridentate and macrocyclic ligands have bee n prepared. The synthesis and structures of a variety of lithium deriv atives are presented since these are the typical starting materials in the preparation of transition metal? main group and lanthanide comple xes that incorporate these ligand systems. It is found that the struct ures of these lithium derivatives depend on the nature of the other do nors present in the chelating array. (C) 1998 Elsevier Science Ltd. Al l rights reserved.
