Synthesis and Characterization of (Pentamethylcyclopentadienyl)Iridium Polyhydride and Polyphosphine Complexes

摘要

Results of investigations in the following areas of research are reported: trimethylphosphine-substituted (pentamethylcyclopentadienyl)iridium complexes; protonation and deprotonation of (C sub 5 (CH sub 3 ) sub 5 )Ir(P(CH sub 3 ) sub 3 )H sub 2 ; synthesis and characterization of poly-trimethylphosphine-(pentamethylcyclopentadienyl)iridium complexes; simulation of ''virtually coupled'' sup 13 C NMR spectra of (C sub 5 R sub 5 )M(P(CH sub 3 ) sub 3 )/sub x/L/sup n+/ species; preparation and reactions of tetrahydrido(pentamethylcyclopentadienyl)iridium: a novel iridium (V) polyhydride; (pentamethylcyclopentadienyl)iridium polyhydride complexes: synthesis of intermediates in the mechanism of formation of (C sub 5 (CH sub 3 ) sub 5 )IrH sub 4 and the preparation of several iridium (V) compounds; NMR spectra of (C sub 5 (CH sub 3 ) sub 5 )IrH sub 2 SiMe sub 3 Li(pmdeta) and (C sub 5 (CH sub 3 ) sub 5 )IrH sub 3 Li (pmdeta): the first direct observation of resolved sup 7 Li - sup 1 H coupling. 116 refs., 13 figs., 9 tabs.
