  • S-alkylation of α-thioether iron compounds by [Ph<sub>3</sub>C]<sup>+</sup>and [Fe(η-C<sub>5</sub>Me<sub>5</sub>)(CO)<sub>2</sub>(CH<sub>2</sub>)]<sup>+</sup>

    Treatment of the thiomethyl complexes [Fe(η-C5Me5)(CO)2(CH2SR)](R = Me or Ph) with [Ph3C]+ or [Fe(η-C5Me5)(CO)2(CH2)]+ results in S-alkylation, affording the sulphonium salts [Fe(η-C5Me5)(CO)2CH2S(R)CPh3}]+ and [Fe(η-C5Me5)(CO)2CH2}2SR}]+ respectively; the former show promise as agents for methylene transfer to alkenes.
    用[Ph3C]+或[Fe(η-C5Me5)(CO)2(CH2)]+处理噻甲基配合物[Fe(η-C5Me5)(CO)2( SR)](R = Me或Ph)会导致S-烷基化,生成砜盐[Fe(η-C5Me5)(CO)2 S(R)CPh3}]+和[Fe(η-C5Me5)(CO)2 }2SR}]+;前者在向烯烃转移亚甲基方面显示出良好的前景。

    Na[(η5-C5Me5)Fe(CO)2](1), a precursor of (η5C5Me5)Fe(CO)2(CH2OMe)(2), is conveniently obtained by Na-Hg reduction of [(η5-C5Me5)Fe(CO)2]2 overnight (20 °C), complex (2) yielding [(η5-C5Me5)Fe(CO)2(CH2PPh3)]BF4(3) upon acid treatment in the presence of PPh3 and converting styrene quantitatively into phenylcyclopropane upon reaction with Me3SiOSO2CF3 giving (η5-C5Me5)Fe(CO)2(OSO2CF3)(4); photolysis of (2)+ PPh3 produces (η5-C5Me5)Fe(CO)-(PPh3)(CH2OMe)(5) which upon acid treatment affords the methylene complex [(η5-C5Me5)Fe(CO)(PPh3)(CH2)]+(6).

    methylidene complexes with unambiguously established molecular and electronic structures remain elusive. In this study, we characterize an iron terminal methylidene complex by single-crystal X-ray diffractometry (scXRD), CHN combustion elemental analysis, 1H/13C/31P/1H–13C NMR, and zero-field 57Fe Mössbauer spectroscopy and study its reactivity. A series of closely related complexes in different oxidation
    亚甲基亚物种被认为是费托过程和烯烃环丙烷化中的中间体,但具有明确建立的分子和电子结构的亚甲基亚配合物仍然难以捉摸。在本研究中,我们通过单晶 X 射线衍射 (scXRD)、CHN 燃烧元素分析、1 H/ 13 C/ 31 P/ 1 H– 13 C NMR 和零场57表征了末端亚甲基配合物。Fe Mössbauer 光谱和研究其反应性。为了验证标题亚甲基配合物的电子结构,合成、分离和表征了一系列密切相关的不同氧化态的配合物。计算分析证实了所提出的 Fischer 型电子描述,同时强调了高 Fe=CH 2键共价键、相当大的双键顺序,因此具有显着的亚烷基特征。
  • Facile conversion of (η5-C5R5) M(CO)2-halide complexes to halomethyl, alkoxymethyl, and cyanomethyl derivatives (R  H, CH3; M  Fe, Ru; halide  Cl, Br, I)

    The CpM(CO)2-X complexes (M = Fe, Ru; X = Cl, Br; CP = eta-5-C5H5, Cp* = eta-5-C5Me5) are completely converted to the corresponding halomethyl derivatives over a 20-30 min period when ethereal diazomethane is added dropwise in the presence of Cu powder. Product work-up involves only simple extraction of the crude product with hexane followed by recrystallization at - 40-degrees-C. Formation of iodomethyl derivatives from iodide precursors requires considerably longer CH2N2 addition times and cannot be completely freed of the starting iodide complexes. Fortunately, iodomethyl complexes can be prepared in 80-95% isolated yield by treating the chloromethyl or bromomethyl derivatives with NaI in acetone/Et2O. The CpFe(CO)2CH2I and Cp*Fe(CO)2CH2I complexes are the most sensitive, decomposing rapidly to polymethylene and the parent iodide complexes upon standing at room temperature. Metathetical reactions of the halomethyl complexes to give alkoxymethyl and cyanomethyl derivatives are described.
