“…Molybdenum hydride complexes are proved more difficult to isolate than their tungsten congeners as a result of their inherent instability . The first reported synthesis of a cuboidal W 3 S 4 trinuclear cluster hydride appeared in 1989 by conversion of the chloro [W 3 S 4 Cl 3 (diphoshine) 3 ] + (diphosphine = dmpe, depe) species to hydrido species according to eq …”

“…Bent metallocene compounds [Cp′ 2 ML 2 ] n + (Cp′ = substituted Cp; Cp = η 5 -C 5 H 5 , M = group IV, V, VI metal) have raised great interest due to their pronounced biological and catalytic activity . The presence of substituents in the cyclopentadienyl rings strongly modulates their catalytic properties through steric and electronic effects.…”

The synthesis and characterization of new ring-functionalized molybdenocene derivatives [CpCp′Mo(CO) 2 ] 2+ and [CpCp′Mo(CO)Br] + (η 5 -C 5 H 4 R; R ) CH 2 CH 2 OMe, CH 2 CH 2 COOEt, CH 2 CH 2 OOCMe, COOMe) are reported. Three alternative routes were used to assemble the CpCp′Mo moiety. Following route I, the unsubstituted precursor [CpMo(CO) 2 (NCMe) 2 ] + reacts with substituted cyclopentadienes (Cp′H) to give after oxidation dicationic compounds [CpCp′Mo(CO) 2 ] 2+ . Alternatively, route II introduces the substituent in the first reaction step upon the synthesis of [Cp′Mo(CO) 2 (NCMe) 2 ] + . In this case, the bis-cyclopentadienyl compounds [CpCp′Mo(CO) 2 ] 2+ were obtained after reaction with cyclopentadiene (C 5 H 6 ) and subsequent oxidation. The NMR spectroscopic measurements prove that the reaction pathways of routes I and II go through different intermediates. The bromo complexes [CpCp′Mo(CO)Br] + were synthesized using route III. Reaction of [Cp′Mo(CO) 2 (NCMe) 2 ] + with C 5 H 5 SiMe 3 gives hydride complexes [CpCp′Mo(CO)H] + . Appropriate bromo complexes were obtained upon reaction with bromine. The ring-functionalized bis-cyclopentadienyl molybdenum(IV) compounds and their monocyclopentadienyl precursors were characterized by spectroscopic methods. Structures of, [(η 5 -C 5 H 4 SiMe 3 )Mo(CO) 2 (NCMe) 2 ][BF 4 ], and [CpMo(η 5 -C 5 H 4 COOMe)(CO)H][BF 4 ] were determined with X-ray diffraction analysis.
