- Abstract
While addition of [Cp2ReH] to [Bi(O tBu)3] leads to an equilibrium containing [Cp2Re-Bi(O tBu)2], [{Cp2Re}2Bi(O tBu)], tBuOH and [CpRe( μ- η5, η1-C5H4)Bi-ReCp2], in the presence of water [{(Cp2Re)2Bi}2O] ( 1) is formed selectively. Also [FpH] [Fp = ( η5-C5H5)(CO)2Fe] can be employed as a precursor to form heterometallic bismuth compounds. Synthesis of [FpBi{OCH(CF3)2}2]2 ( 5) can be achieved by reaction of [FpH] with [Bi{OCH(CF3)2}3(thf)]2 and carboxylates [FpBi(O2CR)2]2 are generated upon treatment of [FpH] with [Bi(O2C R)3] ( R = CH3, tBu). While the compounds [Fp-Bi(O2C R)2]2 can also be obtained from reactions with Fp-Fp, they are formed far more readily using [FpH] as the precursor. They typically crystallize as dimers, like the alkoxide 5. A monomeric compound of the type [Fp-BiX2] ( 6) could be isolated for X = thd (tetramethylheptanedionate), that is, after the reaction of [FpH] with [Bi(thd)3]. Altogether, the results demonstrate the potential of [FpH] as a precursor for [Fp-Bi X2] compounds, which are formed in reactions with bismuth alkoxides, carboxylates and diketonates.
