• W2334201511 abstract "The redox reaction between the europium(III) amide [(Me3Si)2N]3EuIII(μ-Cl)Li(THF)3 and pyrrolyl-functionalized secondary amines was found for the first time. The interactions of 2-(2,6-R2C6H3NHCH2)C4H3NH (R = CH3 (1), R = iPr (2)) with 2 equiv of europium(III) amide [(Me3Si)2N]3EuIII(μ-Cl)Li(THF)3 led to oxidation of the secondary amine with isolation of imino-functionalized pyrrolyl lithium complexes {[η2:η1-2-(2,6-R2C6H3N═CH)C4H3N]Li(THF)}2 (R = CH3 (4), R = iPr (5)). When the deuterated compounds 2-(2,6-R2C6H3NHCHD)C4H3NH (R = CH3 (1a), R = iPr (2a)) were respectively treated with 2 equiv of europium(III) amide [(Me3Si)2N]3EuIII(μ-Cl)Li(THF)3, the corresponding mixture of deuterated imino-functionalized pyrrolyl lithium complexes {[η2:η1-2-(2,6-Me2C6H3N═CD)C4H3N]Li(THF)}2 (4a) and 4 and {[η2:η1-2-(2,6-iPr2C6H3N═CD)C4H3N]Li(THF)}2 (5a) and 5 were produced upon analyses of the NMR spectra of the complexes. Treatment of 2-(2,6-iPr2C6H3NHCHD)C4H3NH (2a) with excess (Me3Si)2NLi gave the only pyrrole deprotonated product, {[η5:η2:η1-2-(2,6-iPr2C6H3NHCHD)C4H3N]Li2N(SiMe3)2}2 (6). When 2-(2,6-iPr2C6H3NHCH2)C4H3NH (2) was treated with ytterbium(III) amide [(Me3Si)2N]3YbIII(μ-Cl)Li(THF)3, a dinuclear ytterbium(III) amide with formula {[(μ-η5:η1):η1-2-[(2,6-iPr2C6H3)NCH2]C4H3N]YbN(SiMe3)2}2 (7) was isolated and no oxidation of the secondary amine was observed. Reduction of ytterbium or imino-functionalized pyrrolyl compound was not observed by refluxing the toluene solution of complex 7 for 2 days. Treatment of equal equivalents of grease (Me2SiO)3, 2-(2,6-iPr2C6H3NHCH2)C4H3NH (2), and europium(III) amide [(Me3Si)2N]3EuIII(μ-Cl)Li(THF)3, after workup, afforded the europium(II) complex {[μ-η5:η1:η1-2-(ArN(Me2SiO)CH2)C4H3N]EuII[η5-2-(ArN═CH)C4H3N]Li2[N(SiMe3)2]}2 (Ar = 2,6-iPr2C6H3) (8) with reduction of europium(III) to europium(II) and oxidation of the secondary amine to an imino group. Reaction of a pyrrolyl-functionalized linked secondary diamine [5-tBu-C4H2NH-2-CH2NHCH2]2 (3) with [(Me3Si)2N]3EuIII(μ-Cl)Li(THF)3 produced a novel centrosymmetric macrocyclic complex with six europium(II) ions and six lithium ions, {[(5-tBu-C4H2N-2-CH═NCH2)2]4[(5-tBu-2-CH3N═CH(C4H2N)]Eu3Li3}2 (9) with observation of redox chemistry between europium(III) and the linked secondary amine. When the linked secondary diamine [5-tBu-C4H2NH-2-CH2NHCH2]2 (3) was treated with [(Me3Si)2N]3DyIII(μ-Cl)Li(THF)3 to produce a novel four-sandwiched-lithium-supported tetranuclear dysprosium(III) complex, {η2:η2-[η1:η1-(μ-η5:η5-[5-tBu-C4H2N-2-CH2NCH2CH2N-2-CH2-5-tBu-C4H2N]Li)2]Dy2(μ3-Cl)Li}2 (10), no redox chemistry was observed. All compounds were characterized by spectroscopic methods and elemental analyses; complexes 4−10 were also characterized by X-ray structure analyses." @default.
