'Synthesis and Application of Large Heterometallic Cluster Systems',
Abstract
A brief introduction to the field of lanthanide organometallics is given covering the chemistry of Ln(II) and Ln(III) compounds. Chapter 1 reports the synthesis and characterization of a range of new oxygen chelating ligands for use in organolanthanide chemistry. The synthesis and characterization of the ligands 2-chloro(1,3,6- trioxaheptyl)benzene (L 1), (1 ,3,6-trioxaheptyl)benzene (L2), 4,6-dichloro- 1,3- bis(1 ,3,6-trioxaheptyl)benzene (L3), and 1,3-bis( 1 ,3,6-trioxaheptyl)aminobenzene (L4) is described. A wide range of lanthanide starting materials (LnCl3, LnCp3, LnCp2Cl) in various oxidation states Ln(O), Ln(II), Ln(III) were reacted with the lithium and sodium salts of the ligands. These salt elimination reactions gave products which demonstrate a number of different coordination modes depending on the nature of the lanthanide used and the ligand. The novel benzyl alcohol with the long ether side-chain (L2) provided the best characterized derivatives. (jg)
