Synthesis of [AsPh4][Fe3(CO)9(μ-CO)(μ 3-HBCl)] by oxidative chloride substitution of [Fe3(CO)9(μ3-HBCO)]2-

The deprotonation of (μ-H)Fe3(CO)9(μ-CO)(μ3-HBH) with n-butyllithium yields the dianionic complex [Li]2[Fe3(CO)9(μ3-HBCO)], which has been spectroscopically characterized. In contrast to the facile reprotonation of closely related ferraboranes, protonation of [Li]2[Fe3(CO)9(μ3-HBCO)] leads to decomposition. On the other hand, reaction of this dianionic complex with 2 equiv of FeCl3 gives a good yield of [Li][Fe3(CO)9(μ-CO)(μ3-HBCl). Metathesis with [AsPh4][Cl] yields [AsPh4][Fe3(CO)9(μ-CO)(μ 3-HBCl)], which has been crystallographically characterized (triclinic, P1, a = 9.534(3) A?, b = 13.305(4) A?, c = 15.225(4) A?, α = 104.39(2)°, β = 103.56(2)°, γ = 99.23(2)°, V = 1768.7(8) A?3, Z = 2). Comparison with the analogous osmium clusters, as well as isoelectronic organometallic clusters, reveals relationships among their structures, properties, and energetics.

Kinetics and mechanism of the reaction of [Et4N][HFe(CO)4] and alkyl halides. The unexpected formation of acetone

When [Et4N][HFe(CO)4] is treated with methyl iodide in CH3CN at 25.0 ± 0.2°C, a clean second-order reaction ensues as monitored via the change in the intensity of νCO of the metal carbonyl hydride. In all cases, yields of CH4 were 85-100%. A second-order rate constant (first order in iron and in CH3I) of (1.7 ± 0.1) × 10-2 M-1 s-1 was determined, and activation parameters of Ea = 11.2 ± 1.0 kcal/mol, ΔH? = 10.6 ± 1.0 kcal/mol, and ΔS? = -33 cal/(mol K) were found over the temperature range 15-35°C. The iron product from this reaction is thought to be the unstable Fe(CO)4(NCCH3) , which can also be generated from Fe(CO)5 in CH3CN by irradiation or use of (CH3)3NO. Reaction of iron hydride with 6-bromo-1-hexene produced only 1-hexene and no detectable methylcyclopentane. Reaction with cyclopropylcarbinyl bromide yielded primarily methylcyclopropane and lesser amounts of 1-butene and cis- and trans-2-butene, although evidence is presented to suggest nonrigorously that this is a side reaction. A simple nucleophilic substitution is proposed as the rate-determining step. During this study acetone was detected and confirmed as a reaction product by isotope-labeling studies. A mechanism for this latter observation is discussed.
