摘要

合成了萘氨基取代硅环丙基钾[(Me3Si)(DIPP)NSi(C10H8)K(THF)2]2 （N-Si-K）。N-Si-K与（II）碘化镱[L1Yb(THF)(μ-I)]2 (L1 = [MeC(NDIPP)CHC(Me)(NCH2CH2NMe2)]−,DIPP = 2,6-(iPr)2C6H3), [L2Yb(μ-I)]2 (L2 = [tBuC(NDIPP)CHC(tBu)(NCH2CH2NMe2)]−)，或[L3Yb(μ-I)]2 (L3 = [MeC（NDIPP)CHC(Me)(NCH2CH2NMe2) CH2CH2NMe2)]−）反应得到相应的（II）硅环丙基配合物1-3。配合物2和3通过单晶x射线衍射进行了表征。配合物2和3不如配合物1稳定，在室温下分解。配合物1与2个等量的三苯基膦硫化物反应生成镱（II）配合物[Yb{MeC(NDIPP)C(Si(NDIPPSiMe3)S2)HC(Me)(NCH2CH2NMe2)}]2(4)并释放萘和PPh3。配合物2与3个等量的1-异氰adamantane反应，通过多个步骤生成不寻常的镱（III）配合物[L2Yb{N(Ad)C}2Si(CN)NDIPP(SiMe3)](5)。

Naphthalene and amino-substituted silacyclopropanyl complexes of ytterbium(II)

A naphthalene and amino-substituted silacyclopropanyl potassium, [(Me₃Si)(DIPP)NSi(C₁₀H₈)K(THF)₂]₂ (N-Si-K), was synthesized. Reactions of N-Si-K with ytterbium(II) iodide [L1Yb(THF)(μ-I)]₂ (L1 = [MeC(NDIPP)CHC(Me)(NCH₂CH₂NMe₂)]⁻, DIPP = 2,6-(ⁱPr)₂C₆H₃), [L2Yb(μ-I)]₂ (L2 = [^tBuC(NDIPP)CHC(^tBu)(NCH₂CH₂NMe₂)]⁻), or [L3Yb(μ-I)]₂ (L3 = [MeC(NDIPP)CHC(Me)(NCH₂CH₂N(Me)CH₂CH₂NMe₂)]⁻) afforded the corresponding ytterbium(II) silacyclopropanyl complexes 1–3. Complexes 2 and 3 were characterized by single crystal X-ray diffraction. Complexes 2 and 3 are less stable than complex 1 and decompose at room temperature. Complex 1 reacts with 2 equivalents of triphenylphosphine sulfide to produce an ytterbium(II) complex [Yb{MeC(NDIPP)C(Si(NDIPPSiMe₃)S₂)HC(Me)(NCH₂CH₂NMe₂)}]₂ (4) and releases naphthalene and PPh₃. Complex 2 reacts with 3 equivalents of 1-isocyanoadamantane to provide an unusual ytterbium(III) complex [L2Yb{N(Ad)C}₂Si(CN)NDIPP(SiMe₃)] (5) through multiple steps.

期刊介绍： Inorganica Chimica Acta is an established international forum for all aspects of advanced Inorganic Chemistry. Original papers of high scientific level and interest are published in the form of Articles and Reviews. Topics covered include: • chemistry of the main group elements and the d- and f-block metals, including the synthesis, characterization and reactivity of coordination, organometallic, biomimetic, supramolecular coordination compounds, including associated computational studies; • synthesis, physico-chemical properties, applications of molecule-based nano-scaled clusters and nanomaterials designed using the principles of coordination chemistry, as well as coordination polymers (CPs), metal-organic frameworks (MOFs), metal-organic polyhedra (MPOs); • reaction mechanisms and physico-chemical investigations computational studies of metalloenzymes and their models; • applications of inorganic compounds, metallodrugs and molecule-based materials. Papers composed primarily of structural reports will typically not be considered for publication.
