Název v původním jazyce

Ring-functionalized molybdenocene complexes

Popis výsledku v původním jazyce

The synthesis and characterization of new ring-functionalized molybdenocene derivatives (CpCpMo(CO)2)2 and (CpCpMo(CO)Br) (C5H4R; R = CH2CH2OMe, CH2CH2COOEt, CH2CH2OOCMe, COOMe) are reported. Three alternative routes were used to assembly the CpCpMo moiety. Following route I, the unsubstituted precursor (CpMo(CO)2(NCMe)2) reacts with substituted cyclopentadienes (CpH) to give after oxidation dicationic compounds (CpCpMo(CO)2)2. Alternatively, route II introduces the substituent in the first reaction step upon the synthesis of (CpMo(CO)2(NCMe)2). In this case, the bis-cyclopentadienyl compounds (CpCpMo(CO)2)2 were obtained after reaction with cyclopentadiene (C5H6) and subsequent oxidation. The NMR spectroscopic measurements prove that the reaction pathways of the routes I and II go through different intermediates. Bromo complexes (CpCpMo(CO)Br) were synthesized using route III. Reaction of the (CpMo(CO)2(NCMe)2) with C5H5SiMe3 gives hydride complexes (CpCpMo(CO)H).
