  Synthesis and characterisation of lanthanide(II) aryloxides including the first structurally characterised europium(II) compound [Eu(OC₆H₂Bu^t₂-2,6-Me-4)₂(thf)₃]·thf (thf = tetrahydrofuran)

  摘要：

  The lanthanide(II) aryloxide complexes [Yb(OC(6)H(2)Bu(2)(t)-2,6-Me-4)(2)(OEt(2))(2)] 1, [Yb(OC(6)H(3)Bu(2)(t)- 2,6)(2)(thf)(3)] 2, [Yb(OC(6)H(2)Bu(3)(t)-2,4,6)(2)(thf)(3)] 3, [Sm(OC(6)H(2)Bu(2)(t)-2,6-Me-4)(2)(thf)(3)] 4, [Eu(OC(6)H(2)Bu(2)(t)- 2,6-Me-4)(2)(thf)(3)].thf 5, [Yb(OC(6)H(2)Bu(2)(t)-2,6-Me-4)(2)(thf)(3)] 6 and [Yb(OC(6)H(2)Bu(2)(t)-2,6-Me-4)l(thf)(x)] 7 (thf = tetrahydrofuran) have been synthesized. Each of the complexes 1-3 was prepared by the reaction of 2 equivalents of the appropriate potassium aryloxide with Ybl(2) in diethyl ether (1) or thf (2 or 3). Complexes 4-6 were prepared by the reaction of 2 equivalents of K(OC(6)H(2)Bu(2)(t)-2,6-Me-4) with Lnl(2)(thf)(2) (Ln = Sm, Eu or Yb) in thf. Reacting Ybl(2) with 1 equivalent of K(OC(6)H(2)Bu(2)(t)-2,6-Me-4) in thf yielded complex 7 as the main product, but Yb-171-{H-1} NMR spectroscopy showed that 6 and [Ybl(2)(thf)(4)] 8 were also formed. The crystal structure of complex 5 reveals that it adopts a distorted trigonal-bipyramidal conformation with (i) apical thf oxygens [O(4)-Eu-O(5) 178.6(2)degrees, Eu-O(4) 2.590(5) and Eu-O(5) 2:573(5) Angstrom]; (ii) the equatorial O(1), O(2) and O(3) thf coplanar; and (iii) Eu-O(1) 2.321(5), Eu-O(2) 2.337(5) and Eu-O(3) 2.515(6) Angstrom. The crystal structure of complex 8 showed there to be an octahedral arrangement around the metal, the molecule lying on a crystallographic inversion centre, with angles l-Yb-O(1) 90.1(2), l-Yb-O(2) 91.4(2) and O(1)-Yb-O(2) 88.9(3)degrees, and bond lengths Yb-l 3.103(1). Yb-O(1) 2.399(9) and Yb-O(2) 2.373(8) Angstrom.

  controlled both by the bulk of the phenol and of the metal. It was noteworthy that EuII complexes were obtained under the conditions used. The method offers a general, environmentally friendly, metal-based route to rare-earth phenolates with prospects for wide application. Some comparison reactions of Ln metals with Hg(C6F5)2 and the phenols were also carried out and the additional complex [Eu(Odpp)3(dme)]

  用 2,6-二叔丁基-4-甲基苯酚 (HOdbmp)、2,6-二苯基苯酚 (HOdpp) 和甲基苯酚 (HOmes) 在乙腈或四氢呋喃 (thf) 中对碘活化的稀土金属进行超声处理，得到 [La (Odbmp)3(NCMe)2], [Eu(Odbmp)2(thf)3], [Ln(Odpp)3(thf)2] (Ln = La, Nd), [Eu(Odpp)2(dme) 2]（用 1,2-二甲氧基乙烷处理后）、[Ln2(Omes)6(thf)4] (Ln = La, Nd)、[Y(Omes)3(thf)3] 和 [Eu3(Omes)6 (thf)6] 在由大量苯酚和金属控制的反应中。值得注意的是，EuII 复合物是在所使用的条件下获得的。该方法提供了一种通用的、环境友好的、基于金属的稀土酚盐路线，具有广泛的应用前景。还进行了 Ln 金属与 Hg(C6F5)2 和酚类的一些比较反应，并分离出额外的配合物
