Arene complexes ferrocene chemistry

Thebis-arene complexes [Re( -C6R6)2] (Re = He, Mee, l,2,3-H3Me3) (140), prepared by the general Fischer-Hafher reaction (equation 27), were first reported in 1957, and the recognition of their sandwich stracture similar to that of Ferrocene, gave decisive impetus to the then novel field of organotransition metal chemistry. ... [Pg.4038]

This chapter summarized recent advances in the reduction chemistry of rare earth metals and described our own efforts in synthesizing inverse sandwiches of rare earth arene complexes using ferrocene-based diamide ligands. Unprecedented molecules were synthesized and their unusual electronic structures were studied. Highlights included the synthesis of the first scandium naphthalene complex and its reactivity toward P4 activation and the isolation and characterization of a 6-carbon, lOTi-electron aromatic system stabilized by coordination to rare earth metals. The reactivity of those complexes was also discussed. [Pg.320]

This group includes an important part of organometallic chemistry, that of arene, ferrocene and cymanthrene complexes and certain complexes of rhodium and iridium. In this case the chiral element is composed of the metal and the prochiral ligand. Figure 2.23 represents the two enantiomers of the 1,2-disubstituted ferrocene complex(2.15). ... [Pg.21]

The review begins with a selective summary of the history of organome-taUic and reductive rare-earth chemistry as an introduction to bimetallic lanthanide complexes bridged by ligands derived from arenes and to complexes of ferrocene-based diamide ligands, a major subtheme in the chapter. Detailed discussions then follow on complexes derived from fused rings and their reactivity with phosphorus and on complexes derived from biphenyl and stilbene as substrates, with emphasis on ferrocene-based diamide complexes. [Pg.347]
